Question

Thorium +4 is reduced in this process. (Thorium metal is prepared by reacting thorium oxide with calcium as shown below.) ThO₂ + 2Ca $\rarr$ Th + 2CaO

Quizplus · Accepted Answer

In the reaction, thorium oxide (ThO2) is reduced to thorium metal (Th) by calcium (Ca). Therefore, thorium +4 is reduced to thorium with no charge, indicating a reduction process.
