Question

What are the products obtained when we bring about thermal decomposition of $CaC{O}_3$?

• A. $CaO$ and $H_{2}O$
• B. $C{O}_2$ and $Ca$
• C. $C{O}_2$ and $CaO$
• D. None of the choices

Answer 1

The correct option is C

$C{O}_2$ and $CaO$

$CaO$ and $C{O}_2$

Thermal decomposition of $CaC{O}_3$ gives $CaO$ and $C{O}_2$. The reaction is considerd as endothermic in nature.

A thermal decomposition reaction occurs when heat is applied to a compound causing it to decompose or break down into multiple different compounds.
