When different compounds react with each other, the reaction between them is written as a chemical equation. A chemical
equation has to always be balanced because the number of atoms of an element reacting has to be the same on both the
sides. Balancing chemical equations calculator is a fun tool very useful in balancing any given chemical reaction.When

Balancing chemical equations calculator is a fun tool very useful in balancing any given chemical reaction.
Example 1: Balance the following chemical reaction:H2 + O2 H2O
Hydrogen atoms:Left side of the equation 2 atoms’.
Right side of the equationè atoms’.
Hence ‘hydrogen atoms’ are already balanced.
Oxygen atoms: Left side of the equation 2 atoms’.
Right side of the equation only ‘1 atom’.
Place a ‘2’ on the right side of the equation: H2 + O2 2H2O
Now oxygen’s are balanced, but there are now ‘4 hydrogen atoms’.
Hence: 2H2 + O2 2H2O
Example 2: Balance the following chemical reaction: Na + HClèNaCl + H2
H:Left side of the equation 1 atom’.
Right side 2 atoms’.
Hence to balance it, we get: Na + 2HCl NaCl + H2
Now ‘H’ isbalanced, but ‘Cl’ is not!
Cl:Left side 2 atoms
Right side 1 atomè Balance by Na + 2HCl 2NaCl + H2
Now ‘Cl’ is balanced, but ‘Na’ is not!
Na: Left side 1 atom,
Right side 2 atoms
Balanced chemical equation 2Na + 2HCl 2NaCl + H2
