A) \[224\,\,g\]
B) \[220\,\,g\]
C) \[400\,\,g\]
D) \[320\,\,g\]
Correct Answer: A
Solution :
\[CaC{{O}_{3}}\xrightarrow{heat}CaO+C{{O}_{2}}(g)\] Lime stone Lime \[(40+12+48)(40+16)\] \[=100\,\,g=56\,\,g\] \[100\,\,g\]of\[CaC{{O}_{3}}\]on burning gives \[56\,\,g\] of\[CaO\]. \[400\,\,g\] of \[CaC{{O}_{3}}\]on burning gives\[=\] \[\frac{56\,\,g}{100\,\,g}\times 400\,\,g=224\,\,g\]
