The unheated gas in the above system has a volume of 20.0 L at a temperature of 25.0 °C and a pressure of 1.00 atm. The gas is heated to a temperature of 100.0 °C while the volume remains constant. What is the pressure of the heated gas?

The pressure of the heated gas is 1.25atm

Explanation:

Using pressure law equation;

P1/T1 = P2/T2

P2 = P1T2 / T1

P1 = 1atm

T2 = 100 C = 100 + 273K = 373K

T1 = 25.0 C = 25 +273K = 298K

Solving for P2 we equate the values and we get;

P2 = P1T2 / T1

P2 = 1 * 373 / 298

P2 = 1.25 atm.

The pressure of the heated gas is 1.25 atm.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
