Explanation The skeletal equation for the formation of aqueous sodium hydroxide and hydrogen gas by the reaction of solid sodium with liquid water by using the chemical formulas of the reactants and products as follows: Na ( s ) +H 2 O ( l ) → H 2 ( g ) +NaOH ( aq ) Chemical equation having an equal number of atoms of each type on both sides is known as a balanced chemical equation. Start with hydrogen as follows: Na ( s ) + H 2 O ( l ) → H 2 ( g ) + NaOH ( a q ) 2 H atoms → 3 H atoms Na ( s ) + 2 H 2 O ( l ) → H 2 ( g ) + 2 NaOH ( a q ) 4 H atoms → 4 H atoms
