Some Basic Concepts Of Chemistry Question 286
Question: n g of substance X reacts with m g of substance Y to form p g of substance R and q g of substance S. This reaction can be represented as, $ X+Y=R+S $ . The relation which can be established in the amounts of the reactants and the products will be
Options:
A) $ n-m=p-q $
B) $ n+m=p+q $
C) $ n=m $
D) $ p=q $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \underset{ng}{\mathop{X}},+\underset{mg}{\mathop{Y}}, $ ⇌ $ \underset{pg}{\mathop{R}},+\underset{qg}{\mathop{S}}, $ $ n+m=p+q $ by low of conservation of mass.
