Question
What gas escapes from the tube in the reaction between carbon and copper(II) oxide?
Solution
The reaction between carbon and copper(II) oxide is a reduction reaction. Here, carbon acts as a reducing agent. The reaction can be represented as follows:
CuO(s) + C(s) -> Cu(s) + CO(g)
In this reaction, carbon reduces the copper(II) oxide to copper. At the same time, the carbon is oxidized to carbon monoxide. Therefore, the gas that escapes from the tube in this reaction is carbon monoxide.
