Question

Which of the following is the best example of law of conservation of mass?
[n and m are the masses of reactants and p and q are the masses of products formed.]

  1. nm=pq
  2. n+m=p+q
  3. n=m
  4. p=q

A
nm=pq
B
n=m
C
n+m=p+q
D
p=q
Solution
Verified by Toppr

Law of conservation of mass:- Mass is neither created nor destroyed it just from one compound to other.

n+m p+q

Hence, the mass of reactants is equal to the mass of products formed.
Option B is correct.
