Answers:
Fission breaks apart nuclei
Fusion puts them together.
======================================================
Explanation:
The term "fission" is related to the term "fissure" which means "a cut or divide", often describing a geologic feature of the earth (eg: a crack in the rock).
Fusion is the idea of putting things together, which is the opposite of fission. The term doesn't have to apply to nuclear fusion. It could be something like the fusing of two ideas to create one new idea.

Answer: The predicted change in the boiling point of water is Δt = 0.0148 °C
Solution:
We will use the equation for boiling point elevation Δt
Δt = i Kb m
where the van't Hoff Factor i is equal to 3 since one molecule of barium chloride in aqueous solution will produce one Ba2+ ion and two Cl- ions. The molality m of the solution of 4.00 g of barium chloride dissolved in 2.00 kg of water can be calculated using the molar mass of barium chloride:
m = [4.00g BaCl2 * (1 mol BaCl2 / 208.233g BaCl2)] / 2.00kg H2O
= 0.009605 mol/kg
Therefore, the amount Δt the boiling point increases is
Δt = i Kb m
= (3) (0.512 °C·kg/mol) (0.009605 mol/kg)
= 0.0148 °C
We can also find the new boiling point T for the solution since we know that pure water boils at 100 °C:
Δt = T - 100°C T = Δt + 100°C = 0.0148 °C + 100°C = 100.0148°C
