Answer:
ugh this wont save anyway i think i'm just checking if ill save
Explanation:
if i does C both
hope this helps
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.

Option 2, Br. I'll go over why all other three options are incorrect.
Option 1 - Krypton is a Noble gas, and so it doesn't need to accept electrons since it has an octet.
Option 3 and 4 - Both Calcium and Barium are alkaline earth metals, and give away electrons, since they only have 2.

Answer:</h3>
4551.37 Pascals
<h3>
Explanation:</h3>
The pressure refers to the force exerted by a substance per unit area.
The pressure is liquid is calculated by;
P = height × density × gravitational acceleration
In this case;
Height = 636.2 mm
Density = 0.7300 g/cm³
g = 9.8 N/kg
We need to convert mm to m and g/cm³ to kg/m³
Therefore;
Height = 636.2 mm ÷1000
= 0.6362 m
Density = 0.73 g/cm³ × 1000 kg/m³
= 730 kg/m³
Then, we can calculate the pressure;
Pressure = 0.6362 m × 730 kg/m³ × 9.8 N/kg
= 4551.3748 pascals
= 4551.37 Pascals
Therefore, the pressure of the column of decane is 4551.37 Pascals
