4.5       predict the products of reactions between dilute hydrochloric, nitric and sulfuric acids; and metals, metal oxides and metal carbonates (excluding the reactions between nitric acid and metals)

acid	type of salt produced
hydrochloric	chloride
nitric	nitrate
sulphuric	sulphate

metal                + acid   → salt + hydrogen

metal oxide       + acid   → salt + water

(or hydroxide)

metal carbonate + acid   → salt + water + carbon dioxide

So, for example, you can deduce that:      magnesium oxide + nitric acid → magnesium nitrate + water.
