Help with this chemistry problem please :) And select the right answer in the brackets :)?

Acids are compounds which dissolve in water giving (Hydrogen/Hydroxide) Ions.Sulphuric acid is one example. It is a (Strong/Weak) acid, which can be neutralized by (acids/alkalis) to form salts called (Nitrates/sulphates). Many (Metals/Non metals) react with acids to give a gas called (Hydrogen/Carbon dioxide). Acids also react with (Chlorides/Carbonates) to give (Chlorine/Carbon dioxide) solutions of acids are (Good/Por) conductors of electricity. They also affect indicators. For example, while litmus turns (Red/Blue). Alkalis are compounds that dissolve in water giving (Hydrogen/Hydroxide) Ions. They have a pH number (Greater/Less) than 7.
