If two gases are present in a container, the total pressure in the container is equal to
a. the sum of the pressures that are exerted by each of the two gases.
b. twice the sum of the pressures that are exerted by the individual gases.
c. the sum of the pressures that each gas would exert if they occupied twice the volume.
d. the sum of the pressures that each gas would exert if they occupied half the volume.

The correct option is (a).

Explanation:

If two gases are present in a container, the total pressure in the container is equal to the sum of the all the individual pressures exerted by the individual gases in a container.

Individual pressure exerted by the individual gas in a container is called partial pressure of that individual gas.

So, total pressure of gas in container is:

Where = Total pressure exerted by the gases in the container.

= Partial pressure of gas 'a'

= partial pressure of gas 'b'

The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.

So, A

Hope this helped :)

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

hope this and sorry i could only come up with one answer!
