⚛️ Chemistry Equation Balancer

What is a Chemistry Equation Balancer?
When we write chemical reactions, it is important to balance the atoms on both sides of the equation.
A balanced equation means that the number of atoms of each element is the same on both the reactant and product sides.

Example:
Unbalanced Equation: H₂ + O₂ → H₂O
Balanced Equation: 2H₂ + O₂ → 2H₂O

Here, both sides have 4 hydrogen atoms and 2 oxygen atoms — so the equation is balanced!

Why is it important to balance equations?
Balancing chemical equations follows the Law of Conservation of Mass, which means that matter cannot be created or destroyed in a chemical reaction — it only changes form.
If an equation is not balanced, the reaction is not scientifically correct.

How to use the Chemistry Equation Balancer:

  1. Write your chemical equation (for example: H₂ + O₂ → H₂O).
  2. Click the “Balance” button.
  3. The calculator will automatically balance the equation and show the result.

Tips:

  • Always check if the number of atoms of each element is the same on both sides.
  • Treat polyatomic ions (like SO₄²⁻, NO₃⁻) as one group to make balancing easier.
  • If you get fractional coefficients, multiply all coefficients to make them whole numbers
