Answer:
81.5 L
Explanation:
We can use the combined gas law equation that gives the relationship among pressure, temperature and volume of gases for a fixed amount of gas.
P1V1 / T1 = P2V2 / T2
where P1 - pressure, V1 - volume and T1 - temperature at the first instance
P2 - pressure, V2 - volume and T2 - temperature at the second instance
substituting the values in the equation
1240 Torr x 47.2 L / 298 K = 730 Torr x V2 / 303 K
V2 = 81.5 L
the new volume the gas would occupy when the conditions have changed is 81.5 L
I think the correct answer would be when ka increases, the acid strength increases. Ka is the product of hydronium ions and the [A-] ions concentration over the acid concentration. Therefore, increasing the the Ka, the numerator in the definition would increase as well which correspondingly increase the strength of the acid.
<h3>Answer: sorry i don't know what the answer that question </h3>
The answer is A, I’m pretty sure, I remember learning this a few years ago, I hope you get it right :)
