<span>When
a solute is added to a solvent, some properties are affected and these set of
properties are called colligative properties. The properties depend on the amount of solute
dissolved in a solvent. For this we use the boiling point elevation of the solution. We do as follows:
</span>ΔT(boiling
point) = 103.06 °C - 100.0 °C= 3.06 °C<span>
ΔT(boiling point) = (Kb)m
m = </span>ΔT(boiling point) / Kb<span>
m = 3.06 °C / 0.512 °C kg / mol
m = 5.98 mol / kg

Theory- <span>a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.
Scientific law- </span>a statement based on repeated experimental observations that describes some aspect of the universe.
Answer: A, metals tend to have lower ionization energies than nonmetals
Explanation:
Got it right on the quiz
Answer:
a item dropping
Explanation:
KE is movement and PE is height. As it's falling it gets KE and falls downward giving it more KE and less PE
Answer:
Chain reaction
Explanation:
A chain reaction is a process by which neutrons that have been released in a first nuclear fission produce an additional fission in at least one more nucleus. This atomic nucleus fishes and releases more neutrons, giving the opportunity to repeat the process.
Nuclear fission is the physical-chemical reaction through which the nucleus of an atom is split. In the main interest of fission reactions is that through this operation a large amount of energy is obtained. According to the definition of nuclear energy, atomic energy is the energy contained in the nucleus of an atom and the energy obtained is thermal energy, energy in the form of heat.
The other form of exploitation is through nuclear fusion reactions. In this case, the process is reverse, merging two different nuclei forming a single atomic nucleus.
After fission of the atomic nucleus we obtain various fragments with a mass almost equal to half of the original mass plus two or three neutrons. It is remarkable the release of these two or three neutrons because they are what will allow a new reaction in another atom.
