The partial pressure of the N2H4 gas is 1.50 atm.
<h3>Dalton's law of partial pressure</h3>
From the Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of the individual partial pressures of all the gases present in the mixture.
We have the following;
C2H2F4 = 3.00 atm
N2H4 = c
Total pressure = 3.00 atm + 1.50 atm = 4.50 atm
Hence, the partial pressure of the N2H4 is N2H4.

<em>I am going to use first-person pronouns for this drop of water</em>
[ Start ] Liquid
I start out as a drop of water among other drops of water in the ocean. I am currently a liquid as I can change shape easily but I do not float up.
[ Middle ] Gas
The sun feels very hot. From the heat I turn into a gas, specifically water vapor, and float up into the sky.
[ Middle x 2 ] Solid
In the sky I meet up with a lot of my past friends. We form a cloud, and as we grow heavier (the more the merrier) we start to fall down. It is extremely cold now, so we fall down as a solid, also known as hail or snow.
[ End ] Liquid
We hit the ocean again as we fall from the sky. I'm so happy to be back home as a water drop again!
Have a nice day! - <u>Please note this is very simplified</u>
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

They vibrate back and forth
the answer is C
It is a chemical change because heat energy is absorbed and the pack gets colder. A change in temperature is a sign that a chemical reaction has taken place; increase in temperature is an exothermic reaction and decrease in temperature is an endothermic reaction. This is an endothermic chemical reaction.
