Question

The figure shows the reaction of magnesium metal. It is an example of an oxidation. Name
the substance reacting with magnesium in the reaction.​

Answer 1

Answer:

The oxidation state of magnesium in the compound is +2 (as magnesium is a member of the second group of the periodic table). When we add the values, we get zero: +2+(-2)=0. This means that the oxidation states have been calculated correctly: for magnesium the value is +2, for oxygen -2 and for hydrogen +1.
