Question

10 g of $MgCO_3$ on heating gives 0.1 mole of $CO_2$ and 4g of $MgO$. This data illustrates:

Answer: A

💡 Solution & Explanation

Reactant $= 10\text{g}$. Products $= (0.1 \times 44) + 4 = 4.4 + 4 = 8.4\text{g}$. (Implicitly assuming remainder is impurity or the system is closed/open, but typically used to verify mass balance in stoichiometry problems).
