On top of be qualitative notes, you must also be able to know how chemical reactions work. For example, is sodium hydroxide reacts with something to form sodium chloride, the something must be hydrochloric acid since bases (alkalis, in this case) can only react with acids AND the acid must contain Cl since sodium chloride contains Cl.

Here are my explanations for these questions. Sorry that my explanations are very wordy. And I am not sure if you have learnt oxidation and reduction yet. Let me know if my explanations are unclear and I will do my best to explain them in greater detail.
