Answer: 670K
Explanation:
Given that,
Original volume of gas V1 = 1.22 L
Original temperature T1 = 286 K
New volume V2 = 2.86 L
New temperature T2 = ?
Since volume and temperature are involved while pressure is constant, apply the formula for Charles law
V1/T1 = V2/T2
1.22 L/286 K = 2.86 L/ T2
Cross multiply
1.22 L x T2 = 286 K x 2.86 L
1.22T2 = 817.96
Divide both sides by 1.22
1.22T2/1.22 = 817.96/1.22
T2 = 670.459 K (Round to the nearest whole number as 670 K)
Thus, the temperature of the gas is 670 Kelvin

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).
