Answer: 310K
Explanation:
Given that:
Volume of Chlorine gas V = 10.2L
Temperature T = ?
Pressure P = 1.83 atm
Number of moles of chlorine gas N = 0.734 moles
Molar gas constant R is a constant with a value of 0.0821 atm L K-1 mol-1
Then, apply ideal gas equation
pV = nRT
1.83atm x 10.2L= 0.734 moles x 0.0821 atm L K-1 mol-1 x T
18.67atm L = 0.0603 atm L K-1 x T
T = (18.67atm L / 0.0603 atm L K-1)
T = 309.8K (Round up to 310K)
Thus, the temperature of the chlorine gas is 310 kelvin
It is a salt and salt salt and
The molar mass of the hydrate is 278.06
The molar mass of the anhydrous salt is 151.92
The molar mass of water in the hydrate is 126.14
The volume of the drum after chilled quickly is 3.6 L.
<u>Explanation:</u>
As per the Charles Law, for any gas at constant pressure, volume of the gas is in direct proportion with the temperature measured in Kelvin. As the temperature increases, the gas expands and vice versa.
After chilling the drum, the volume will get reduced and it can be found as,
V2 = 
= 
= 3.6 L
Here the drum is chilled quickly, that is temperature is reduced and so the volume also decreases.
Answer:
Who contributed the most to the atomic theory?
After Democritus' discovery, new evidence would be found that would eventually lead to the modern atomic theory. John Dalton, J.J. Thompson, Ernest Rutherford, Niels Bohr, James Chadwick and Ernest Schrodinger each contributed greatly to the modern atomic theory by finding the actual evidence.
