Which of the following reactions is not correct according to the law of conservation of mass ?

A

`2Mg(s) + O_(2)(g) to 2MgO(s)`

B

`C_(3)H_(s)(g) to CO_(2)(g) + H_(2)O(g)`

C

`P_(4)(s) + 5O_(2)(g) to P_(4) O_(10)(s)`

D

`CH_(4) (g) + 2O_(2)(g) to CO_(2)(g) + 2H_(2)O(g)`

Text Solution

Verified by Experts

The correct Answer is:
B
In this equation,
`C_(3)underset(44g)(H_8(g)) + underset(44g)(CO_(2)(g)) + underset(18g)(H_(2)O(g))`
i.e., mass of reactants `ne` mass of products
Hence, law of conservation of mass is not followed.
