Question

Copper reacts with Oxygen vigorously at room temperature.

• A. True
• B. False

Answer 1

The correct option is B False

• Oxidation is the process of losing electrons, the gain of Oxygen or the loss of Hydrogen.
• Copper ($\mathrm{Cu}$) does not react with Oxygen(${\mathrm{O}}_2$) at room temperature.
• But heated Copper metal reacts with Oxygen to form black Copper oxide($\mathrm{CuO}$).
• Chemical equation: $\underset{\mathrm{Copper}}{2\mathrm{Cu}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Copper}\mathrm{oxide}}{2\mathrm{CuO}\left(\mathrm{s}\right)}$

Therefore the given statement is false.
