Options

A. 2.16 g
B. 2.48 g
C. 2.32 g
D. 2.64 g

Answer

A

Explanation

`Ag_(2)CO_(3)` on strong heating gives Ag
`underset(276g)(Ag_(2)CO_(3)overset(Delta)(to)underset(2xx108g)(2Ag)+CO_(2)+1//2O_(2)`
276g of `Ag_(2)CO_(3)` on strong heating gives
= 216 g of Ag
2.76g of `Ag_(2)CO_(3)` on strong heating gives
2.16 g of Ag
