Question

Ca is oxidized in this process. (Thorium metal is prepared by reacting thorium oxide with calcium as shown below.) ThO₂ + 2Ca $\rarr$ Th + 2CaO

Quizplus · Accepted Answer

The equation shows that Ca is combined with a compound (ThO2) to form a different compound (CaO) while making Thorium metal. In this process, Ca is losing electrons, which means it is undergoing oxidation. Therefore, the statement "Ca is oxidized in this process" is true.

Ca Is Oxidized in This Process →\rarr→ Th + 2CaO

Ca Is Oxidized in This Process $\rarr$ Th + 2CaO
