Answer:
A. Molecules have finite volume.
Explanation:
Gases deviate from the ideal gas law at high pressures because its molecules have a finite volume.
Real gases have a finite volume which enables more interaction between the molecules while ideal gases are assumed not to have a finite volume or occupy space which is why it lacks any form of interaction between its molecules.
This difference is the deviation between the real and ideal gases.
Answer:
B. 0.7%
Explanation:
Given data:
Actual boiling point = 82.5°C
Experimental boiling point = 83.1°C
Percent error = ?
Solution:
Formula:
Percent error = ( actual value - experimental value / actual value )×100
by putting values,
Percent error = (82.5°C - 83.1 °C /82.5°C) × 100
Percent error = 0.007 × 100
Percent error = 0.7 %
Negative sign shows that experimental value is greater than accepted value. It can not written in result.
Answer : The mass of liquid sodium needed are, 
Explanation :
First we have to calculate the number of moles of liquid sodium.

where,
q = heat absorb = 1.20 MJ = 1.20 × 10⁶ J
n = number of moles of liquid sodium = ?
c = specific heat capacity = 
= change in temperature = 
Now put all the given values in the above formula, we get:


Now we have to calculate the mass of liquid sodium.
Molar mass of Na = 23 g/mol


Therefore, the mass of liquid sodium needed are, 
Answer: oh my gosh, yes I relate with this so much. Don’t worry, you are not alone and you will get through this.
