Balancing Chemical Equations

Chemical Equations Quick Check

A chemical equation shows the starting materials called reactants and the products made by the reaction. The arrow on the left side of the equal sign indicates that the reaction proceeds in one direction.

A balanced chemical equation obeys the law of conservation of mass and is written so that the numbers of atoms of each element are the same on both sides of the equation. This is achieved by adding stoichiometric coefficients to the formulas.


In chemical equations, the little number that follows an element symbol is called a subscript. It indicates how many atoms of that element are in a molecule. For example, the 2 in H2O shows that there are two oxygen atoms per water molecule.

Students should always know that the big number in front of a chemical formula (coefficient) is multiplied by the little number that follows the symbol for the element to find the total number of atoms in the molecule of the compound or substance. The result should match the numbers in the reactants and products sides of the chemical equation.

The term stoichiometric coefficients refers to the number of atoms or molecules of each element that is needed in a reaction to balance it. When balancing chemical equations, students should focus on balancing the stoichiometric coefficients first. This strategy is sometimes referred to as “balancing by inspection”. It involves looking at the numbers of atoms of each type of molecule in the reactants and products, then adding the stoichiometric coefficients to make sure that the total number of atoms is the same on both sides of the chemical equation.


A chemical equation is a written description of what happens during a reaction. It lists the starting materials, called reactants, on one side and the products made by the reaction on the other. A plus sign separates the two sides and an arrow indicates the direction of the reaction. Chemical reactions often break bonds and produce new molecules. The numbers of each type of atom on each side must match to comply with the Law of Conservation of Mass, which states that matter is never created or destroyed but always rearranged.

The small whole numbers that appear in front of the formulas are known as coefficients. They help you balance the chemical equation by matching the number of atoms of each type on both sides. For example, if there are 3 carbon atoms on the left side of the equation and 2 on the right, you can balance it by adding a coefficient of 3. This increases the number of carbon atoms on the right side of the equation to match the number of oxygen atoms in the products.


Chemical equations show the relationship between the initial substances (reactants) and the new substances that form when a reaction takes place. The reactant substances are written on the left side of the equation and the product substances are on the right. A line (called an arrow) separates the two sides of the equation. An arrow pointing to the right means that the reaction is proceeding forward, while an arrow pointing down means that the reaction is occurring backward.

The arrow is balanced by changing the coefficients on either side of the arrow. A coefficient is a number that appears in front of a chemical formula and provides the ratio between the chemical species on each side of the arrow.

In addition to the arrow, chemical equations also contain symbols that indicate the state of matter for each substance. If a chemical is a solid, the symbol is (s). If it is liquid, the symbol is (l). If it is gaseous, the symbol is (g). The shorthand notation for an aqueous solution is (aq). In some chemical reactions, a symbol called delta can be used above the arrow to indicate that the reaction requires energy in the form of heat.


A chemical equation is a written representation of a chemical reaction. It shows the reactants on the left and the products on the right. A plus sign separates them and an arrow indicates the direction of the reaction (reactants form products). The law of conservation of mass states that the number of atoms in the reactants must be equal to the number of atoms in the products.

To balance an unbalanced chemical equation, start with one of the least complex substances and work your way up to the most complex. Then, use a trial and error method of adjusting the coefficients until the number of atoms is the same on both sides of the equation.

The process of balancing an equation sounds simple enough, but it’s actually quite difficult to do. It requires a lot of practice and common sense. It’s important to check your work, especially if you’re using fractional values for the stoichiometric coefficients.

Cheaper Alternatives to Diamonds: Moissanite, Cubic Zirconia, White Sapphire, and Lab Grown Diamonds

Cheaper Alternatives to Diamonds

There are several diamond alternatives available to suit individual preferences and budgets. These include moissanite, cubic zirconia, white sapphire, and lab grown diamonds.

If you’re not adamant on a certain gemstone shape, you could save around 10% by choosing less popular cuts. Remember, though, that not all stones are as hardy as diamonds and may become dull over time.

1. Moissanite

Moissanite is the most wallet friendly diamond alternative gem, offering the best sparkle and durability. It also comes in several different colors and shapes and is available in both round and princess cut.

It is made of silicon carbide and was discovered in 1893 by a French chemist named Henri Moissan. It was originally thought to be a diamond until it was determined that they did not possess the same molecular structure as real diamonds. Moissanite is considered a diamond simulant, meaning that it is crafted to mimic the visual characteristics of natural diamonds.

Another popular choice is cubic zirconia, which is a lab created gemstone that can be shaped to look very similar to a diamond. This option is much more affordable than diamonds and offers a brilliant sparkle that can be seen even in dim lighting. However, it is not as durable and may need to be re-polished after some wear and tear.

2. Cubic Zirconia

If you’re looking for a diamond alternative, cubic zirconia is one of the best options on the market. Although it isn’t as durable as moissanite or diamonds, it’s much cheaper and still a beautiful gem in its own right.

CZ is a crystal that was first discovered in Russia in the 1970s and is made in a laboratory. While it’s not a natural mineral, CZ is just as hard as diamonds and looks very similar. In fact, it can be difficult to tell the difference between a diamond and a cubic zirconia by sight alone.

While CZ is a good choice for those on a tight budget, other options like Moissanite and lab grown diamonds offer more durability and a closer look to natural diamonds. So if you’re interested in a real diamond, we recommend sticking with those options.

3. White Zircon

As its name suggests, White Zircon is a natural diamond substitute. It is mined in East Africa and usually heated to achieve its colorless appearance, but it is sometimes found in unheated forms. It is a very affordable gemstone, much less expensive than a real diamond.

While diamonds and white zircon may appear similar at first glance, they differ in their composition, hardness, and price. Understanding gemstone properties like refractive index and dispersion allows individuals to select a gemstone that will provide the best value for their individual needs and budget.

Whether choosing a natural sapphire for its durability, moissanite for its brilliance, or lab grown diamonds for their cost effectiveness, each gemstone offers unique benefits that can appeal to different preferences and budgets. Educating yourself about the various characteristics of gemstones ensures that you will be satisfied with your selection for years to come. This article originally appeared in Rock & Gem magazine. Click here to subscribe!

4. Lab Grown Diamonds

Lab diamonds are human-made, chemically, physically and optically identical to natural ones — so only specialist equipment can distinguish them. They are also ethically sourced (instead of mined) and have a smaller environmental impact than mined diamonds.

Because they are so new to the market, however, it isn’t known how well lab grown diamonds will hold their value over time. For this reason, if you’re considering a piece of jewelry that you might want to sell or pass down in the future, we would recommend a natural diamond.

Still, if you’re an eco-conscious buyer looking to make a socially responsible purchase, lab diamonds are worth considering! And the options are ever-growing. One of our favorite places to shop for lab created pieces is Blue Nile. They prioritize customer education and provide transparent pricing so you can find the best deal. Plus, they work with respected vendors who adhere to the Kimberley Process standards so you can feel confident about their sourcing.

Chemical Substances in Your Home

4 Chemicals in Your Home

The average home contains a lot of chemical products. These include paint, linseed oil, lacquer varnish, epoxies, denatured alcohol and bleach.

Many of these chemicals are toxic if ingested or inhaled. Others are harmful if touched or sprayed on skin and eyes. Some are even carcinogens. The Food and Drug Administration approves over 10,000 chemical additives to food — 99 percent of them greenlighted by food and chemical companies since 2000.

1. Benzo[a]pyrene

Benzo[a]pyrene (C20H12) is an aromatic hydrocarbon composed of a benzene ring fused to a pyrene ring. It is a polycyclic aromatic hydrocarbon, environmental pollutant and carcinogen. It is released into the air by incomplete combustion of fuels such as tobacco smoke, diesel engine exhaust and wood burning. It is then bioactivated to form highly reactive diol epoxides that can react with DNA. Benzo[a]pyrene diol epoxide can cause DNA damage by forming covalent adducts with guanine bases. This forms abasic lesions that interfere with DNA replication and can result in mutations.

It is believed that this process induces lung cancer through its effects on cellular DNA and mitochondrial function. It also induces immunosuppression and reproductive toxicity. It is a known human carcinogen that acts as a chemical mutagen by producing chromosomal mutations in the K-RAS oncogene and TP53 tumour suppressor gene.

2. 1,3-Butadiene

1,3-Butadiene is a volatile diene used in the manufacture of synthetic rubber. It is also a useful intermediate in the Diels-Alder reaction. Inhalation exposures to butadiene result in irritation of the eyes and nose. Exposure to large amounts can cause unconsciousness and death.

Inhalation studies with B6C3F1 mice exposed to butadiene showed clear evidence of carcinogenicity at concentrations of 625 ppm or greater. Tumors included hemangiosarcoma of the heart and alevolar/bronchiolar adenomas or carcinomas. Mammary gland adenomas and granulosa cell tumors of the ovary were also seen in female mice.

Butadiene is mutagenic in somatic cells of mice and rats. It is also genotoxic in germ cells of mice. Butadiene is listed as a hazardous air pollutant. The Clean Air Act requires major sources to sharply reduce routine emissions of this pollutant.

3. Butyraldehyde

Butyraldehyde is a colorless liquid that is soluble in organic solvents. It is an intermediate in the production of synthetic resins, rubber accelerators, solvents, plasticizers, and high molecular weight polymers.

The production and use of butyraldehyde may release the compound into the environment via wastewater and gaseous emissions from various sources(SRC). The vapor phase degrades rapidly in an ambient atmosphere by reaction with photochemically produced hydroxyl radicals and by direct photolysis.

Butyraldehyde is irritant to the skin, eyes, and respiratory system. It may form explosive peroxides when exposed to air. Exposure to acetaldehyde and malonaldehyde has been shown to produce nasal tumors in rats and laryngeal tumors in hamsters. NIOSH considers butyraldehyde a potential occupational carcinogen. It has also been shown to be mutagenic in laboratory animal experiments.

4. Cadmium

Cadmium is used in the production of metal plating, nickel-cadmium batteries for mobile phones and cordless equipment, plastics, and paint pigments. It is also released in air during smelting, soldering and other high-temperature industrial processes.

The toxicity of cadmium is due to its accumulation in the body tissues. The kidneys and skeleton are most affected by cadmium. It can induce a range of pathologies in the renal tubular system from proteinuria to deterioration of renal function and renal cancer.

Exposure to cadmium can be mediated by breathing contaminated dust or eating contaminated food and drinking water. Long-term exposure to low levels of cadmium can lead to lung damage and high blood pressure. It can also cause osteomalacia (weak painful bones) and emphysema. High levels of cadmium in the air can cause respiratory irritation and heart disease.

5. Catechol

Catechol is a brown-colored solid or aqueous solution with faint characteristic odor and is used in rubber, chemical, photographic, dye, fat and oil industries. It is also employed as a developer for fur dyes and as an antioxidant in metal plating and specialty inks. It was formerly used as an antiseptic.

Catechol reacts with a variety of biomolecules and generates a wide range of reactive oxygen species (ROS). These ROS damage DNA, proteins and membranes leading to non-repairable lesions.

Treatment of groups of Fischer 344 rats with catechol (0 or 1.5% in diet) increased the incidence of forestomach papillomas induced by N-methyl-N’-nitrosomethyl-N-nitrosoguanidine but not glandular stomach adenocarcinomas (Yamaguchi et al, 1989). Catechol also inhibits the rate-limiting step of DNA synthesis and leads to chromatin condensation in cultured human T lymphocytes.

G-Shock Alternatives: Casio Pro Trek, Ana-Digi Temp, G-Steel, MR-G, AW-500

G-Shock Alternatives

Celebrities like Eminem, Pharrell Williams, and Bradley Cooper love their G-shocks. They are tough enough to survive the apocalypse and are designed to last generations.

If you’re looking for a high-end alternative to a G-Shock, check out the Casio Pro Trek series. These tough hiking watches have triple sensor features (altimeter, compass and thermometer) but have a different look.

Ana-Digi Temp

With its boxy silver form and angular bisection of displays, the Ana-Digi Temp positively reeks of the 1980s. Yet, despite its retro aesthetic, this is one of the most groundbreaking timepieces to ever come out of Japan.

It incorporated analog and digital components, including dual time functionality, alarms, a chronograph, an ambient temperature sensor, and display back lighting. The result was a timepiece that was lightweight, durable, and extremely functional.

In the end, it was the Ana-Digi Temp that helped usher in a new era of tech-driven tool watches. Its influence can still be seen today in Casio’s G-Shock line of watches.

The Ana-Digi Temp was reissued in 2018 as part of Citizen’s collaboration with Japanese retail chain BEAMS. The collection included six different Star Wars-themed Ana-Digi Temp watches, each based aesthetically on a specific character or element from the film series. The most popular is this gold C3P0 model, but there are also R2D2, Darth Vader, and Boba Fett versions available as well.


If G-Shock is known for anything, it’s its substantial, ready-for-anything watches. But that’s not always the most comfortable look for slimmer wrists, so Casio has introduced its thinnest G-Steel yet with this GSTB400-1A model.

The new case uses a carbon core guard structure to achieve its low weight, high strength, and chemical resistance. It also eliminates the need for shock-resisting button guards and reduces the amount of metal used in the design. The GSTB400 also has a front LED light button that makes it easy to read the time in dim conditions.

Unlike other G-Steel models, this one features a chronograph function with an analog display and a dual-coil motor in the rotating dial at 9 o’clock. The watch also has Bluetooth connectivity that connects to your smartphone and synchronizes your time with the internet time server. All of this is packed in a watch that is both durable and elegant. It’s the perfect G-Shock for people who want to stay connected and still have an unbreakable timepiece.

G-Shock MR-G

The MR-G line represents the pinnacle of G-Shock’s engineering and bulletproof capability. It is characterized by its use of premium materials and a rugged aesthetic. The watches are made with a flat sapphire crystal that is armored by the bezel, which protects the glass from direct contact with objects that could shatter it. They also have a number of other features, including an alarm, a chronograph, and an altimeter.

This watch is part of the Full Metal MR-G series, which uses titanium and other advanced materials to showcase the brand’s Japanese heritage. Its dial was designed with the traditional Japanese kachi-iro color, which is dark navy blue and has a rich history in Japan. It was favored by samurais as a “winning” color and was used on their armor and helmets.

The MR-G line is meant to appeal to an older demographic, as opposed to the MG series, which caters to teenagers. These models are nigh-indestructible, and are crafted from premium materials such as titanium and fluoroelastomer rubber.

G-Shock AW-500

Originally launched in 1989, the AW-500 Series shattered the then widely held belief that analog watches are easily susceptible to shock due to their delicate hands and gears. This reissue of a classic features basic stopwatch and timer functions, along with an EL backlight and seven-year battery life.

This model is available in popular mud black or mud red hues and offers a unique dial presentation, fulfilling G-SHOCK’s promise of 200-meter water resistance and drawing on inspiration from diver’s watch design with a layout featuring a triangular marker and minute-displaying index.

In the 1980s, Casio understood that to appeal to a younger audience, they needed to use street culture in their marketing. The brand started using rappers, skaters, and fashion designers to promote their products, which helped them become a cultural phenomenon. Their newest models are no exception. The new AW-500D-1A8 looks like the original, but is lighter and has a more modern module. The watch also includes an EL backlight, so you can read the dial in the dark.
