I would like to understand the temperature at which a substance will vaporize when dissolved in a liquid. I have researched this online for hours, but haven't found a conclusive answer. Is it the boiling point of the dissolved substance? I'm attempting to find the temperature at which caffeine vaporizes when dissolved in water or other vegetable glycerin.

I hope this helps a little bit
<span>Mass number is the number of protons and neutrons in an atom, and it tells us about the mass of the atom in amu, or atomic mass units. </span>
<span>Atomic mass is the average mass of all the isotopes of a certain type</span>
<u>Given:</u>
Moles of gas, n = 1.50 moles
Volume of cylinder, V = 15.0 L
Initial temperature, T1 = 100 C = (100 + 273)K = 373 K
Final temperature, T2 = 150 C = (150+273)K = 423 K
<u>To determine:</u>
The pressure ratio
<u>Explanation:</u>
Based on ideal gas law:
PV = nRT
P= pressure; V = volume; n = moles; R = gas constant and T = temperature
under constant n and V we have:
P/T = constant
(or) P1/P2 = T1/T2 ---------------Gay Lussac's law
where P1 and P2 are the initial and final pressures respectively
substituting for T1 and T2 we get:
P1/P2 = 373/423 = 0.882
Thus, the ratio of P2/P1 = 1.13
Ans: The pressure ratio is 1.13
Answer:
It's A
Explanation:
It starts as one molecule and splits into two which is the definition of a decomposition reaction
Answer:
Inhibitor
Explanation:
Inhibitors generally slow down a reaction rate and prevent the particles from reacting with each other.
It's not the others because:
Catalysts work by lowering the activation energy, which in turn increases the reaction rate as more particles have enough energy to react.
Surface area allows for particles in the reaction to collide more often with each other, which increases the reaction rate.
Temperature increases the speed of particles in the reaction, causing particles to collide more often with each other and therefore increasing the reaction rate.
