The mathematical relationship between gas solubility and pressure is called Henry's Law, solubility = kHPgas where kH is the Hen

ry's Law constant for a gas at a given temperature. What is kH for Ar at 25 °C, in units of mol/L•mm Hg?

Answer : The unit of k_H in mol/L.mm Hg is, 1.8\times 10^{-6}mol/L.mmHg

Explanation :

As we know that the k_H is the Henry's Law constant for argon at 25^oC is, 1.4\times 10^{-3}mol/L.atm

Now we have to determine the unit of k_H in mol/L.mm Hg

Conversion used for pressure from atm to mmHg is:

1 atm = 760 mmHg

So,

k_H=1.4\times 10^{-3}mol/L.atm\times \frac{1atm}{760mmHg}

k_H=1.8\times 10^{-6}mol/L.mmHg

Thus, the unit of k_H in mol/L.mm Hg is, 1.8\times 10^{-6}mol/L.mmHg

Answer:
it’s quite simple.
The newton force in a aerodynamic space which could lead to a catastrophic entanglement will be added to the physical quantum molecular structure then subtracted by its opposite, inter dimensional indispensable aerobic activity, then finally multiplied by the sum which was subtracted by the addition to then divide the sum of it all with the solution of the multiplication which would equal to the answer.

1. Which combinations of substances resulted in a chemical change?(no answer choices)
Lunna [17]

All chemical reaction between substances results into a chemical change. When two substances just like HCL and NaOH reacts with each other, NaCl means Sodium Chloride salt is formed.  

The phenomenon like change in color, change in temperature, release of gas etc when happens ,then it means chemical change has been occurred. e.g

HCl +NaOH ----> NaCl +H2O.
