Answer:
-Acetone is a covalent compound, while sodium chloride is an ionic compound
-covalent compounds have weak attractions between molecules, resulting in low melting points
Explanation:
Charge = number of proton - number of electron = 18-22 = -4

Answer:
energy is the capability or ability to do work
Explanation:
An object that possesses energy can exert a force on another object. When this happens, energy is transferred from the former to the latter. The second object may move as it receives energy and therefore does some work. Thus, the first object had the capacity to do work.
Convection: the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
