The total volume of water that would be removed will be 75 mL
<h3>Dilution equation</h3>
Using the dilution equation:
M1V1 = M2V2
In this case, M1 = 500 mL, V1 = 10.20 M, M2 = 12 M
Substitute:
V2 = 500 x 10.20/12
= 425 mL
The final volume in order to arrive at 12 M HNO3 would be 425 mL from the initial 500 mL. Thus, the total amount of water that will be removed by evaporation can be calculated as:
500 - 425 = 75 mL

Answer:

Explanation:
Hello,
In this case, since the rms speed of the molecules is computed by:

Whereas the absolute temperature is computed from the internal energy (by using the Cp of helium (3.1156 J/g*K) as shown below:

Thereby, the rms speed results:

When 2 different kinds of matter make contact, if they react to each other, they simply exchange atoms, not making any new matter in the process, they simply gets turned into something different.
