2.76 g  of silver carbonate  on being strongly heated yields a residue weighing

Answer:

Explanation:

Silver carbonate on being strongly heated decomposes as 

$Ag_{2}CO_{3}$ $\underrightarrow{\triangle}$ $2Ag+CO_{2}+\frac{1}{2}O_{2}$

276 g                               216g

 As 276 g of $Ag_{2}CO_{3}$ gives =216g of Ag

 Hence , 2.76 g of $Ag_{2}CO_{3}$ will give 

 $=\frac{2.76 \times 216}{276}=2.16g$
