Non-polar covalent
Explanation:
Propane is made up of non-polar covalent bonds and it can be expected to dissolve in hexane and to not dissolve in water.
Propane is an hydrocarbon gas.
It forms by sharing of electrons between two atoms with very low electronegativity differences.
This differences results in equal sharing of the shared electron. Therefore they form a non-polar covalent bond.
Water is a polar covalent compound and cannot dissolve compounds that are not polar like propane.
Propane will only dissolve in a like substance like hexane which is equally non-polar.

Answer:
D
Explanation:
D states a problem because of the population growing. Regulate means control and d stated that their was a problem and a need to control it. Therefore, d I'd really the only valid answer.
Answer: The kinetic theory of matter states that all matter is made of small particles that are in random motion and that have space between them. And since gases have even more energy than liquids, their particles are moving around a lot more, too.
Explanation:
Answer:
D
Explanation:
I believe it is D. your kinetic energy would be at b. A, the cart would be going at a constant rate, because there is no hill or steep slope.
