Answer:
Option B. PV = nRT.
Explanation:
From the above,
C = PV / T. (1)
But, C is directly proportional to n, where R is the gas constant i.e
C & n
C = nR
Substituting the value of C into equation (1), we have:
C = PV / T
nR = PV / T
Cross multiply to express in linear form
nRT = PV
Therefore,
PV = nRT
It is logical to assume that they hydrogen ion concentration in an aqueous solution of a strong monoproctic acid equals the molarity of the acid because ions which are charged,for example ammonium ion (NH4+), which can be derived by the addition of a proton to a molecular base.

Answer:
B. It undergoes a physical change.
Explanation:
Hello there!
In this case, since we know that chemical changes lead to the formation of new atoms and/or compounds due to the bonds rearrangement of the initial substances and the physical changes occur without changing the composition of the initial substances, we can infer that, since melting is a process that changes the phase of matter from solid to liquid without changing the identity of the initial substance, the answer to this question would be B. It undergoes a physical change. because the other options describe chemical changes.
Best regards!
