Answer:
pKa = 9
Explanation:
In this case, we have to remember the meaning of "p". When we use "p" in any calculation we have to apply the minus ten based logarithm, so:
For example, when we use the "pH" value. We have to apply the minus ten based logarithm of the concentration of the hydronium ion:
![pH~=~-Log[H^+]](https://tex.z-dn.net/?f=pH~%3D~-Log%5BH%5E%2B%5D)
So, if we have wanted to calculate the pKa value. We have to apply the minus ten based logarithm of the Ka value, so:
Now we can plug the value into the equation:
<u>The pKa value is 9.</u>
I hope it helps!
The answers to you questions are 3,66 g of liquid water and 0,84 g of vapor.
Solution:1) Q₁ = mxCxΔT = 4,5 g x 2,108 J/°C x g x 10°C.
= 97,86 J heat required to warm the ice to 0°C.
2) = 4,5 g x 334 J/g. = 1503 J heat required to melt the ice to water at 0°C.
3) = 4,5 g x 4,184 J/°C x g x 100°C
= 1882,28 J heat required to warm the water from 0°C to 100°C. = 5400 J - 3483,14 J = 1916,86 J heat left to vaporize the water.
mass of the vapor= 1916,86 J ÷ 2257 J/g
= 0,84 g.
