Answer: increases
Explanation:
Matter exists in three different states, they are solids, liquids and gases. And each of them contains molecules with a certain amount of kinetic energy.
Hence, the addition of heat changes a substance from a liquid to a gas through a process called vaporization, whereby liquid molecules on changing to gases acquire a higher kinetic energy, and move more freely within the containing vessel.
Thus, the higher kinetic energy explains the increase in the average distance between molecules.
CaCl₂ (aq) + K₂CO₃ (aq) → CaCO₃ (s) + 2 KCl (aq)
where:
(aq) - aqueous
(s) - solid
Explanation:
Calcium chloride (CaCl₂) will react with potassium carbonate (K₂CO₃) to produce solid calcium carbonate (CaCO₃) and potassium chloride (KCl).

Answer: I am not sure but I think its fossil fuel - filling oil and mining coal cause few environmental problems,not dependent on weather condition, not chemical hazard or flammable hazard. Wind and solar - inexpensive, increase carbon footprint and easily stored and transported
Explanation:
I am not quite sure for two of them
I would believe the answer is:
.9211 ATM
9.51 L
