When calcium oxide is heated with carbon, the oxide will
-
be converted to carbide
- be converted to the trioxocarbonate (IV) salt
- decompose to the metal
- melt, producing carbon (IV) oxide
The correct answer is: A
Explanation
When calcium oxide (CaO) reacts with carbon (C), it produces calcium carbide (CaC\(_2\))and carbon monoxide (CO). This reaction occurs at very high temperatures, around 700°C.
CaO + 3C → CaC\(_2\) + CO
