What do you mean by Chemical equations?
A chemical equation is a written representation of the chemical reaction taking place between two or more substances. It can be written in words or symbols, and typically consists of the reactants (on the left side) and the products (on the right side). The arrow between them indicates the direction of the reaction.
The above equation is balanced because it has the same number of atoms of each element on both sides of the equation. The equation is balanced because it has 4 atoms of nitrogen (N) on the left side and 4 atoms of nitrogen on the right side. It has 5 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side. It also has 3 atoms of hydrogen (H) on the left side and 12 atoms of hydrogen on the right side.
