<u>Answer:</u>
It is the expression of Charles' Law.
<u>Explanation:</u>
The given expression V1T2 = V2T1 is the formula for the Charles' Law.
A special case of an ideal gas is named as the Charles' Law. This law applies to ideal gases only which are at constant pressure.
According to this law, the volume of a fixed mass of a gas is directly proportional to its temperature and is given by:
V1T2 = V2T1
Density is mass over volume, so:
14.3/8.46≈ 1.6903 g/cm^3
The species that is the conjugate acid is HC₂H₃O₂(aq). The correct option is d.
<h3>What are conjugate acid?</h3>
Conjugates acids are those acids which are made when an acid donates a proton to a base according to Bronsted Lowry theory.
In other words, we can say that it is an acid with hydrogen ion. An example is water (base) reacting with an acid to form the hydronium ion (conjugate acid).
Thus, the correct option is d, HC₂H₃O₂(aq).
