Consider the chemical reaction that takes place between the metal magnesium and sulfuric acid. As a result of this reaction, we see the formation of a salt of magnesium sulfate, hydrogen sulfide and water. In order to equalize this reaction, we need to put the number 4 in front of the magnesium, and put the number 5 in front of the sulfuric acid. In the reaction products, we also put the number 4 in front of the magnesium salt and the number 4 in front of the water. The molecular equation of the reaction can be written as follows:
4 Mg + 5 H2SO4 = 4 MgSO4 + H2S + 4 H2O.
