## 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)

When they are written, both types show the reactants on the left of an 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. A bit like a one-way street, you can’t reverse along a one-way street as well as you can’t reverse an irreversible 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. This tool actually performs as to balance the given equation, it calculates the coefficients. There is an algorithm used named Gauss-Jordan elimination but slightly modified.

## How to Use Chemical Equation Balancer Calculator

Just enter your unbalanced equation at given space and press “Balance”. Avoid irrelevant spaces. The use of all parentheses must be correct. The equation can be in lowercase letters. But if the elements are already properly capitalized, it will be fine and not be changed. And properly use arrow sign etc

## How a Chemical Equation Balancer Calculator Works?

Now, I am going to describe how to balance chemical equations. In this example, let me show you what happens when you mix iron (Fe) with two molecules of oxygen (O2). When these mix 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. Your 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.

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

So let’s get started to balancing this equation. First let’s start with the iron 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 of the equation 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. Notice 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 here one and half times two is equal to three and on the right-hand side, we have three atoms of oxygen. So now it is balanced. 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.

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

$$\text{4Fe}\;\;+\;\;3O_2\;\;\rightarrow\;\;2Fe_2O_3$$

Now we have a balanced chemical equation. Chemical equation balancer also works on the same way.
