Carbon can reduce copper oxide to copper but not CaO to Ca. Why?

Text Solution

AI Generated Solution

To understand why carbon can reduce copper oxide (CuO) to copper (Cu) but cannot reduce calcium oxide (CaO) to calcium (Ca), we need to analyze the reactivity of metals and the concept of reducing agents. ### Step-by-Step Solution: 1. **Understanding the Reactivity Series**: - The reactivity series is a list of metals arranged in order of decreasing reactivity. In this series, potassium is the most reactive, followed by sodium, calcium, magnesium, and so on, with gold and platinum being the least reactive. 2. **Position of Calcium and Copper**: ...
