\(x\) grams of calcium carbonate was completely burnt in air. The weight of the solid residue formed is \(28 \mathrm{~g}\). What is the value of \(x\) (in grams)?
- A 44
- B 200
- C 150
- D 50
Answer & Solution
Correct Answer
(D) 50
Step-by-step Solution
Detailed explanation
\(\begin{array}{lc} \mathrm{CaCO}_3(s) \stackrel{\Delta}{\longrightarrow} \mathrm{CaO}(s)+\mathrm{CO}_2(\mathrm{~g}) \\ 40+12+48 & 40+16 \\ =100 & =56 \end{array}\) \(\therefore \quad 56 \mathrm{~g} \mathrm{CaO}\) is obtained from \(=100 \mathrm{~g} \cdot \mathrm{CaCO}_3\)…
