The balancing chemical equations calculator takes instants to balance any chemical equation. Just input an unbalanced equation or molecule name and it will determine the right numbers of each required to balance the equation.
This calculator displays the balanced equations, their structure with equilibrium constant, and substance properties with chemical names and formulas.
What Is a Chemical Equation?
In chemistry:
“A chemical equation shows the overall chemical change of reactants into products”
Example:
Consider the following equation:
$$ \text{NaOH}\;\;+\;\;\text{HCl}\;\rightarrow \text{NaCl}\;\;+\;\;H_{2}O $$
In the above equation, caustic soda and hydrochloric acid react with each other to form a couple of products which are sodium chloride and water.
Process of Writing Chemical Equations:
While writing a chemical equation, the reactants are on the left before the arrow and the products are on the right.
The arrow (→) shows the direction of the reaction and shows that the reaction is irreversible. If in the equation there is a plus sign (+) then it indicates that there is more than one reactant or product on each side of the equation.
Types of Chemical Equations:
There are two types of chemical equations including:
1. Word Equation:
In this equation, all reactants and products are represented by their full descriptive names.
$$ \text{Sodium} + \text{Chlorine}\rightarrow\text{Sodium Chloride} $$
2. Symbol Equation:
In a symbol equation, all parameters are represented by their periodic table symbols.
$$ H_{2} + O\rightarrow2H_{2}O $$
How To Balance Chemical Equation?
Consider the following chemical reaction equation:
$$ \text{Fe}\;\;+\;\;O_{2}\;\;\rightarrow\;\;Fe_{2}O_{3} $$
To balance this equation manually, 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. To make them equal, add the number of two molecules on the left-hand side as follows:
$$ \text{2Fe}\;\;+\;\;O_{2}\;\;\rightarrow\;\;Fe_{2}O_{3} $$
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. So, on the left-hand side apply two atoms of oxygen with one and a half molecules.
$$ \text{2Fe}\;\;+\;\;1.5O_{2}\;\;\rightarrow\;\;Fe_{2}O_{3} $$
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 molecules of oxygen. We can also find the molecular weight so, how can we get rid of this half molecule? The answer to this question is to multiply both sides by 2.
$$ 2*\text{2Fe}+2*\text{1.5O_{2}}\rightarrow 2Fe_{2}O_{3} $$
$$ \text{4Fe}+\text{3O_{2}}\rightarrow 2Fe_{2}O_{3} $$

Frequently Asked Questions:
What Are The Main Types of Chemical Equations?
Every chemist has to deal with certain chemical schemes that involve the following:
- Precipitation reaction
- Combination reaction
- Combustion reaction
- Decomposition reaction
- Neutralization reaction
- Single and double replacement reaction
- Synthesis reaction
What Happens If Chemical Equation Is Not Balanced?
If a chemical reaction is not balanced, you can never get any information about the reactants or products involved in it. This will let you know what proportion did every reactant invested to make the final product.
What Are The Three Limitations of Balanced Chemical Equation?
- Never informs about the physical state of the chemical reaction
- Never tells the exact concentration and dilution amounts of reactants and products
- Never tells if a chemical reaction is reversible or irreversible
