To check the principle of multiple proportions, a series of pure binary conmpouds ( $\mathrm{P}_{\mathrm{m}} \mathrm{Q}_{\mathrm{n}}$ ) were analyzed and their composition is tablulated below. The correct option(s) is(are)
Select ALL correct options:
A
If empirical formula of compound $\mathbf{3}$ is $\mathrm{P}_3 \mathrm{Q}_4$, then the empirical formula of compound $\mathbf{2}$ is $\mathrm{P}_3 \mathrm{Q}_5$.
B
If empirical formula of compound 3 is $P_3 Q_2$ and atomic weight of element $P$ is 20 , then the atomic weight of Q is 45 .
C
If empirical formula of compound $\mathbf{2}$ is PQ , then the empirical formula of the compound $\mathbf{1}$ is $\mathrm{PsQ}_4$.
D
If atomic wight of $P$ and $Q$ are 70 and 35 , respectively, then the empirical formula of compound $\mathbf{1}$ is $\mathrm{P}_2 \mathrm{Q}$.
