Vedclass · Answer

(D) Sodium bicarbonate $(NaHCO_3)$ decomposes on heating to form sodium carbonate,water,and carbon dioxide: $2NaHCO_3 \rightarrow Na_2CO_3 + H_2O + CO_2$. Calcium carbonate $(CaCO_3)$ decomposes on heating to form calcium oxide and carbon dioxide: $CaCO_3 \rightarrow CaO + CO_2$. Sodium carbonate $(Na_2CO_3)$ is stable to heat and does not decompose under ordinary heating conditions. Therefore,both $(A)$ and $(C)$ decompose on heating.

Compound	Percentage proportion
$1. CaO$	$d. 50-60\%$
$2. Al_2O_3$	$a. 5-10\%$
$3. SO_3$	$b. 1-3\%$
