  • Calculator just tries to balance the equation. It cannot predict products.
  • Reagents are sufficient to make an equation, e.g. H2 O2 H2O. Signs '+' or '=' are optional, however must be separated with spaces from reagents when introduced, e.g. H2 + O2 => H2O
  • One can try balance half reactions. Ions should be depicted with square or round braces like these: H[+], SO3(2-), Cu[+2].
  • Electrons e[-] must not be specified in half reactions.

What is a Chemical Equation?

A chemical equation shows the overall chemical change of reactants into products. The reactants are what you start with and the products are what are formed. There are two ways of writing chemical equations- word equation and symbol equation.

$$\text{NaOH}\;\;+\;\;\text{HCl}\;\rightarrow\;$$

$$\text{NaCl}\;\;+\;\;H_2O$$

Sodium Hydroxide (NaOH)
Hydrochloric Acid (HCl)
Sodium Chloride (NaCl)
Water (H2O)

How Chemical Equation is written?

While writing chemical equation, the reactants are on the left before arrow and the products on the right. The arrow ---> is there to show that the reaction is irreversible. It shows the direction of the reaction. The plus sign indicates that there is more than one reactant or product on each side of the equation.

A word equation provides a good summary but a symbol equation provides more detail. It shows more information and allows us to see how many atoms and molecules are involved in each reaction.

Introduction of Chemical Equation Balancer Calculator

Balancing chemical equations calculator works in sensible manners as there is artificial intelligence is doing work. balancing equations calculator performs as to balance the given equation, it calculates the coefficients.

There is an algorithm used named Gauss-Jordan elimination but slightly modified. Balancing chemical equations calculator is free and easy to use.

How a Chemical Equation Balancer Calculator Works?

If we mix iron (Fe) with two molecules of oxygen (O2) together, you get compound (Fe2O3) and what is commonly known as rust. So this is a good example to show what happens when you leave your bicycle in the rain.

Bicycle is mostly made up of steel. Steel is 95% percent fine but the iron mixes with the rain which is just water and water contains oxygen. So the iron and oxygen combine together and then you get this annoying brown substance on your bike which is Fe2O3 and you know it as rust.

$$\text{Fe}\;\;+\;\;O_2\;\;\rightarrow\;\;Fe_2O_3$$

To balance this equation, we need to have the same number of iron on the left-hand side as we do on the right-hand side. So on the left-hand side it has one atom of iron and on the right-hand side it has two atoms of iron. So just to make them equal, add the number of two molecules on the left-hand side.

$$\text{2Fe}\;\;+\;\;O_2\;\;\rightarrow\;\;Fe_2O_3$$

So, now do the same with the oxygen. On the left-hand side, we have two atoms of oxygen but on the right-hand side we have three atoms of oxygen. We need to make it equal. So, on the left-hand side apply two atoms of oxygen with one and a half molecules.

$$\text{2Fe}\;\;+\;\;1.5O_2\;\;\rightarrow\;\;Fe_2O_3$$

Now we have the same exact number of iron and oxygen on the left-hand side as on the right-hand side. But we return with a problem because there is never half molecule noticed.

But we noticed here we have one and half a molecule of oxygen. So how can we get rid of this half molecule? The answer of this question is multiply both sides by two.
