NEET · Chemistry · STD 11 - 1. Some basic concept of chemistry
The right option for the mass of \(CO _2\) produced by heating \(20 g\) of \(20 \%\) pure limestone is \(........\,g\)(Atomic mass of \(Ca =40\) )\(\left[ CaCO _3 \stackrel{1200 K }{\longrightarrow} CaO + CO _2\right]\)
- A \(1.32\)
- B \(1.12\)
- C \(1.76\)
- D \(2.64\)
Answer & Solution
Correct Answer
(C) \(1.76\)
Step-by-step Solution
Detailed explanation
