Answer:
The answer to your question is: the third option is correct.
Explanation:
"Alkenes" ________.
are reasonably soluble in water This option is incorrect, alkenes are insoluble in water.
are relatively polar compounds This option is wrong, alkenes are not polar molecules.
have lower boiling points than alcohols of similar molecular weight This option is true, alkenes have a lower boiling point than alcohols.
both have lower boiling points than alcohols of similar molecular weight and are relatively polar compounds. This option is incorrect because is combining true with false facts.
Answer:
Alkanes contain only carbon-carbon and carbon-hydrogen bonds. Because carbon and hydrogen have similar electronegativity values, the C—H bonds are essentially nonpolar. Thus, alkanes are nonpolar, and they interact only by weak London forces.

Answer: a) No, both are different.
b) Ramesh- 9.9%
Sarika - 10%
Explanation:
According to the solution prepared by Ramesh,
Mass of sugar he took (Solute) = 10 g
Mass of water he took (Solvent) = 100 g
Thus Mass % of the solution =
According to the solution prepared by Sarika,
Mass of sugar she took (Solute) = 10 g
Mass of Solution she took = 100 g
Thus Mass % of the solution =
Explanation:
Answer:
no its condensation
Explanation:
evaporation is when water.. well evaporated and condensation is when water condenses into liquid from a gas
