Complete the reaction equation a) compounds: Li + O2 =; Ai + O2 = b) decomposition: AgCl = c) substitutions: AI + CuO =

a) Reaction of the compound:

Interaction of lithium and oxygen, with the formation of lithium oxide.

Li + O2 = LiO2;

The interaction of aluminum and oxygen, with the formation of aluminum oxide.

Al + O2 = AlO2
b) Decomposition reaction:

Dissociation under the influence of temperature of the silver chloride salt into silver and chlorine. The chemical reaction equation can be written as follows:

2 AgCl = Ag2 + Cl2

c) Substitution reaction:

Aluminum reacts with copper oxide to form alumina and pure copper. The chemical reaction equation looks like this:

Al + 2 CuO = AlO2 + Cu2.
