Question

In an experiment, $m$ grams of a compound $X$ (gas/liquid/solid) taken in a container is loaded in a balance as shown in figure I below. In the presence of a magnetic filed, the pan with $X$ is either deflected upwards (figure II), or deflected downwards (figure III), depending on the compound $X$. Identify the correct statements(s)

• A. If $X$ is $H _{2} O (l)$, deflection of the pan is upwards.
• B. If $X$ is $K _{4}\left[ Fe ( CN )_{6}\right]$ (s), deflection of the pan is upwards.
• C. If $X$ is $O _{2}(g)$, deflection of the pan is downwards.
• D. If $X$ is $C _{6} H _{6}(I)$, deflection of the pan is downwards.

Answer 1

Answer: (A), (B), (C)

If $X$ is $H _{2} O (l)$, deflection of the pan is upwards.

Answer 2

(A) If $X$ is $H _{2} O (l)$, deflection of the pan is upwards.
(B) If $X$ is $K _{4}\left[ Fe ( CN )_{6}\right]$ (s), deflection of the pan is upwards.
(C) If $X$ is $O _{2}(g)$, deflection of the pan is downwards.
