Answer:
b) The boiling point of the solution is always greater than the boiling point of the pure solvent.
Explanation:
Hello,
In this case, when we add a nonvolatile solute to a volatile solvent which has a relatively low boiling point, we can evidence the increase of the boiling point of the resulting solution as more energy must be supplied to take the molecules from liquid to gas. This fact matches with the boiling point elevation colligative property due to the solute's addition, which states that the boiling point of the solution is always greater than the boiling point of the pure solvent, therefore, answer is b).
Best regards.
Answer: A
Explanation:
Plants take in sunlight, water, carbon dioxide. The produce sugar (glucose) and other things. It could not be deforestation. It can't be evaporation, that is from the water cycle. It cant be C due to it talking about precipitation, which is also from the water cycle. Therefore, it can only be A
