Explanation:
Detailed explanation-1: -Because each water molecule, H2O, contains only one oxygen atom, two water molecules must form for each oxygen molecule that reacts. The coefficient 2 in front of the H2O(l ) makes this clear.
Detailed explanation-2: -Balanced equation shows the reaction between aluminium hydroxide and hydrochloric acid to form aluminium chloride and water . Al(OH)3+ 3HCl⇒AlCl3+3H2O.
Detailed explanation-3: -The balanced chemical equation that describes this single replacement reaction looks like this: 2Al(s)+6HCl(aq)→2AlCl3(aq)+3H2(g)
Detailed explanation-4: -Hence, when aluminum hydroxide neutralizes hydrochloric acid a salt aluminum chloride and water are formed.
