Chemical Equation & Chemical Combination (Chemical Bonding)

Chemical reactions can be represented by a chemical equation. The reactants are written on the left-hand side (L.H.S) of the equation while the products are on the right-hand side (R.H.S). 

\( \scriptsize \underset{L.H.S}{REACTANTS} \; \rightarrow \; \underset{R.H.S}{PRODUCTS} \)

Balancing Chemical Equation:

Equations must be balanced in order to agree with the law of conservation of mass which states that in an ordinary chemical reaction, matter can neither be created nor destroyed.

An unbalanced equation would imply that atoms have been created or destroyed. For example, when hydrogen reacts with oxygen to form water, the chemist writes the equation for the reaction as:
