Answer
Salt and water
Explanation
When a metal oxide reacts with an acid, the products are typically salt and water, which is a neutralisation reaction.
Common mistake
Confusing Neutralisation with Other Reactions
Students often confuse the neutralisation reaction between metal oxides and acids with other types of reactions, failing to recognize that it specifically produces a salt and water.
To fix this, students should focus on the definition of neutralisation as the reaction between an acid and a base (metal oxide) that results in the formation of a salt and water, and practice writing balanced equations for these reactions.
