This kind of questions cannot be open because there might be many different answers depending of the focus.
In fact, I found the set of options that comes with this questions. This is:
A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.
Of course, the answer is the option D. molecular motion.
And, of course, you need an explanation.
It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.
With that you likely had been able to answer the question. But it is good to know what the molecular theory is.
The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.
Answer:
Energy is absorbed, and an emission line is produced.
Explanation:
Electrons are present and revolving continuously in the orbits that are present around the nucleus. The energy of electron are fixed and unable to move to other orbits due to the strong attractive force of the proton which is present in the nucleus of the atom. If the electron wants to jump from the first energy level to the second energy level, so the electron has to absorb enough energy which can overcome the attractive force of proton.
I think it's Letter c.13 if I'm not mistaken
A simple way to go about this is that we look at the solubility curve, on the x axis we first look at the temperature and then the corresponding value of solute/100g H2O on the y axis, from the 4 curves above only NaNO3 has a curve that can accommodate 80g of salt at 40 without being Saturated since at 40 degrees it can accommodate 105g of salt to become completely Saturated.
