Calculate the residue obtained on strongly heating `2.76g Ag_(2) CO_(3)`.

A

1.16 g

B

2.16 g

C

3.16 g

D

4.16 g

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(,Ag_(2)CO_(3),rarr,2Ag,+,CO_(2),+,(1)/(2)O_(2)),("Initially","0.01 moles",,-,,-,,-),("Finally",,,"0.02 moles",,"0.01 moles",,"0.005 moles"):}`
`"Mass of residue" = 0.02 xx 108 = 2.16 g`
