(chem question MULTIPLE CHOICE) What is the old pressure when the new pressure is 850 mmHg, and the final temperature is 1058.75 K and the original temperature is 90.0oC. The volume of its container is increased by moving a piston from 85.0 mL to 350.0 mL.

multiple choice:

2428.40 mmHg

10208.33 mmHg

17.55 mmHg

1200 mmHg

c.

explanation:

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.
