How do I complete and balance an equation for reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH)?
(2)HCl + (2)NaOH→ (2)NaCl + (2)H2OH total left = 4, Cl total left = 2, Na total left = 2, O total left = 2H total right = 4, Cl total right = 2, Na total right = 2 O total right = 2first balance the Cl and Na, then hydrogens, then oxygens. always balance the oxygens last.total = 8
