NEET UG CHEMISTRY MCQ: SOME BASIC CONCEPTS OF CHEMISTRY

Choose the corrcct statements.

(a) Double decomposition method is based on the law of equivalent.

(b) For a reaction, ${P}_{m} {Q}_{{n}}+{R}_o {S}_{{p}} \longrightarrow \text{products}$

If amount of $P_m Q_n$ reactcd $=w_1$ gm

and amount of $R_o S_p$ reacted $=w_2$ gm, then

$\frac{w_1}{w_2}=\frac{\text {Equivalent wt. of } R_o S_p}{\text {Equivalent wt. of } P_{m} Q_{n}}$

(c) For a rcaction $P_{m} Q_n+R_o S_p \longrightarrow \text{products}$

If amount of $P_m Q_n$ reacted $=w_1$ gm

and amount of $R_o S_p$ reacted $=w_2$ gm, then

$\frac{w_1}{w_2}=\frac{\text {Equivalent wt. of } P_m Q_n}{\text {Equivalent wt. of } R_o S_p}$

(d) 1 equivalent of oxygen $=16 \mathrm{~gm}$
