When the pressure that a gas exerts on a sealed container changes from blank torr to 900 torr the temperature changes from 300 k to 450 k

Initial pressure = 600 torr

Explanation:

Given:

Initial pressure, P1 = 900 torr

Initial Temperature, T1 = 300 K

Final temperature, T2 = 450 K

To determine:

Final pressure of  gas, P2

Explanation:

Based on the ideal gas equation

where n = moles of gas

R = gas constant, T = temperature

At constant volume (V), the above equation becomes:

P/T = constant

This is Gay-Lussac's law

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.
