Which types of orbitals are found in the principal energy level n = 3

Zina [86]

Answer: 3s, 3p, and 3d

Explanation: those are the 3 types of orbitals that are found in n=3. lets say it was energy level orbitals in energy level n=4, then the answer would be 4s, 4p, and 4d if that makes sense. I hope you found this helpful! Have a great day!

The answer to your first question would be A.) since for every molecule of C being produced, 2 molecules of B are consumed.

As for the second question. Since you used an arrow pointing only right we infer that this reaction isn't reversible. Decreasing the volume of the container would mean that more collisions occur per unit of time. Thus the rate of the reaction increases.

The equation used to calculate the change in freezing point (ΔTf) of a substance is:_______

Elenna [48]

Answer:

B. As the temperature of a solution changes, its volume will also change, which will affect its molarity but not its molality.

Explanation:

Molality is given by the following equation:

$Molality = \frac{moles of solute}{kg of solvent}$

While the molarity formula is given as

$Molarity=\frac{moles of solute}{Lof solvent}$

The volume of solvent changes with temperature so it will be impractical to use molarity as it accounts for the volume of solution in its formula, which will create an error. Molality, on the other hand, uses Kg of solvent; which is not dependent on temperature. Hence, its value will not change
