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).
Example:
Here are two examples of reactions of different metals with dilute acids:
Magnesium + Hydrochloric Acid → Magnesium Chloride + Hydrogen
