`1`mole each of `CaCl_2, Al_4C_3, Mg_2C_3` reacts with excess water in separate open flasks work done during the dissolution shows the order:

A

`CaC_(2)=Mg_(2)C_(3) lt Al_(4)C_(3)`

B

`CaC_(2)=Mg_(2)C_(3)=Al_(4)C_(3)`

C

`Mg_(2)C_(3) lt CaC_(2) lt Al_(4)C_(3)`

D

`Mg_(2)C_(3) lt Al_(4)C_(3) lt CaC_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
In `Al_(4)C_(3)`, there moles of `CH_(4)` are formed.
