Question
You are given the following chemical equation:
\[\ce{Mg_{(s)} + CuO_{(s)} -> MgO_{(s)} + Cu_{(s)}}\]

combination reaction as well as double displacement reaction.
redox reaction as well as displacement reaction.
double displacement reaction as well as redox reaction.

Solution
Redox reaction as well as displacement reaction.
Explanation:
This is a displacement reaction because the more reactive metal, magnesium (Mg), displaces the less reactive metal, copper (Cu), from its oxide compound. It is simultaneously a redox reaction because magnesium gains oxygen (undergoes oxidation) while copper oxide loses oxygen (undergoes reduction).
