Options:

A) 2.16 g

B) 2.48 g

C) 2.32 g

D) 2.64 g

Show Answer

Answer:

Correct Answer: A

Solution:

[a] Decomposition of $ Ag _2CO _3 $ gives silver $ \underset{\begin{smallmatrix} 2\times 267g \\ 2.76g \end{smallmatrix}}{\mathop{2Ag _2CO _3}},\to \underset{\begin{smallmatrix} 4\times 108g \\ 2.16g \end{smallmatrix}}{\mathop{4Ag+}},2CO _2+O _2 $
