Answer:

Explanation:
- State of benzene at RTP = liquid
- State of chloroform at RTP = liquid
- Boiling point of benzene = 80.1 °C
- Boiling point of chloroform = 61.2 °C
Since, both of the chemicals are liquids, we can separate it by the process of distillation.
<u>Distillation:</u>
- is the process in which we separate two liquids on the basis of their difference in boiling points.
<u>How it works:</u>
Since chloroform has less boiling point, it will evaporate and collected first and benzene will follow it after sometime.
- Apparatus of distillation is in the attached file.

Answer: option B. 5g
Explanation:
50mL of H2O dissolves 25g of CaCl2.
Therefore, 10mL of H2O will dissolve Xg of CaCl2 i.e
Xg of CaCl2 = (10 x 25) /50 = 5g
C is the answer to the problem
