A) \[n-m=p-q\]
B) \[n+m=p+q\]
C) \[\operatorname{n} = m\]
D) \[p = q\]
Correct Answer: B
Solution :
\[\underset{ng}{\mathop{X}}\,\,\,+\underset{mg}{\mathop{Y}}\,\,\,\rightleftharpoons \,\,\underset{pg}{\mathop{R}}\,\,\,+\,\,\underset{qg}{\mathop{S}}\,\] \[\operatorname{n} + m =p + q\] by law of conservation of mass.You need to login to perform this action.
