Answer:
the mineral formed when a hot water solution cooled
Answer:

Explanation:
Hermione is pretty smart. She realizes that, according to Dalton's Law of Partial Pressures, each gas exerts its pressure independently of the others, as if the others weren't even there.
She shows Ron how to use the Ideal Gas Law to solve the problem.
pV = nRT
She collects the data:
V = 1.00 L; n = 0.0319 mol; T = 25.0 °C
She reminds him to convert the temperature to kelvins
T = (25.0 +273.15) K = 298.15 K
Then she shows him how to do the calculation.

Isn't she smart?
Answer:
electrons are transferred from the clouds to the grounf
Explanation:
Answer:

Explanation:
Hello,
In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:

So we solve for
by firstly computing the initial pressure:


Finally, we can compute the work by using the following formula:

I think it will be D or B but my mine answer is D
