As we learnt.

Dalton's Atomic Theory -

Chemical Reactions invovle reorganization of atoms. Atoms are neither created nor destroyed in a chemical reaction.

- wherein

CaCO_{3}\rightarrow CaO + CO_{2}

The number of atoms on both sides of the equation are same

 

 

 

Using Dalton's atomic theory, we have:

Blancing A

x -y = 2\;\;\;-(1)

In B,

 x + y = 6\;\;\;-(2)

In D, 

z = 3

from (1) & (2),

x =4

y = 2

\therefore Solution is D
