The balanced chemical equation for the reaction between barium hydroxide, Ba(OH)₂ and HNO₃ to produce barium nitrate, Ba(NO₃)₂ is
Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O
What is a chemical equation?
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
How to write the balanced equation
Ba(OH)₂ + HNO₃ —> Ba(NO₃)₂ + H₂O
There are 2 atoms of N on the right side and 1 atom on the left side. It can be balanced by writing 2 before HNO₃ as shown below:
Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + H₂O
There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balanced by writing 2 before H₂O as shown below
Ba(OH)₂ + 2HNO₃ —> Ba(NO₃)₂ + 2H₂O
Now, the equation is balanced
