From the Graham's law of effusion;
R1/R2 = √MM2/√MM1
Molar mass of chlorine gas is 71
Therefore;
1.87= √ 71 /√mm1
= 1.87² = 71/mm1
mm1 = 71/1.87²
= 71/3.4969
= 20.3
Thus, the molar mass of the other gas is 20.3 , and i think the gas is neon
Answer:
acid precipitation is an agent of
Explanation:
Answer: b
Explanation:
By adding heat you are adding more energy
Energy can be renewable or nonrenewable.
Answer:
Equilibrium will lie to the right.
Explanation:

That means HF is stronger acid than
.
Alternatively, it can be said that
is a stronger base than
.
Therefore HF readily gives proton to
to form
and
than the reverse reaction.
So, the equilibrium will lie more towards the right i.e. towards formation of
and
.
