Answer:
LD is a answer okkkkkkkkkkkkkkkkk
I would say that it's true
The answer is (D) - The Particles gave no set ratio for how to combine, and they can be separated by physical means.
Mixtures can be separated through means or filtration, evaporation, and sublimation. No chemical process or chemical reaction/bonding takes place. Thus, which is why It can be separated by physical means because it’s still technically in it’s own individual elements.

To convert from moles to molecules, simply multiply the
number of moles by the Avogadros number which is about 6.022 x 10^23 molecules
/ moles.
Taking the O2 for example:
molecules of O2 = 1.30 moles * (6.022 x 10^23 molecules /
moles)
molecules of O2 = 7.83 x 10^23 molecules
I believe you can do for the rest. Just follow the same
steps.
For the last question.
