Some Basic Concepts Of Chemistry Question 89
Question: 2.76 g of silver carbonate (at mass of Ag 108) on being heated strongly yield a residue weighing
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 $
