Concept introduction:Law of conservation of mass, total reactants consumed equalstotal products formed in any balanced equation.
In order to balance an equation, one starts with the most complex chemical formula and then place the appropriate coefficient so as to make the stoichiometric coefficient equal on each side.
After proper adjustment of coefficient, the atoms are checked for an equal number on each side and finally, the physical states of matter are written in parenthesis.
