This worksheet tests a student's ability to understand the reactions between Metals and Acids.
First off, when an acid reacts with a metal, the acid will react with the metal to produce the metal salt of that acid; at the same time it will produce hydrogen gas.
What does that look like? The general path of these metal/acid reactions is:
Acid + Metal Salt + Hydrogen
(NB: note that the word 'salt' here refers to a metal salt, i.e. a compound of the metal which has been formed through reaction with an acid, e.g. zinc chloride, potassium nitrate and iron sulfate are all metal salts).
Here are two examples of reactions of different metals with dilute acids:
Magnesium + Hydrochloric Acid → Magnesium Chloride + Hydrogen
