Actualy the answer is Lower pressure causes the papers to come closer together.
Please mark brainiest if this is correct and helpful.
First, we convert the masses into fractions
<span>138 g of benzene = 1.77 moles benzene
91.2 g of heptane = 0.93 moles heptane
Next, calculate the mole fractions
x1 (benzene) = 1.77 / (1.77 + 0.93) = 0.66
x2 (heptane) = 1 - 0.66 = 0.34
</span>The vapor pressure of pure benzene is 322 torr at 40 C.
At the same temperature, the vapor pressure of heptane is 92 torr.
<span>
The partial pressure of benzene is
p1 = 0.66 (322) = 212.52 torr
The partial pressure of heptane is
p2 = 0.34 (92) = 31.28 torr

Assuming you have multiple choices... According to the internet, this question is a multiple choice question.
Here are following answers.
"The environmental change that occurs faster is definitely volcanic eruption. It may happen in an instant and destroy everything in its way, whereas the process of regrowth of forest after volcanic eruption is a slow one."
Oil spills may also have the fastest occurring changes in the environment.

Explanation:
Atomic number = 1
Mass number = 1
Proton = 1
Neutron = mass number - atomic number
= 1 - 1
= 0
