When a gas is heated,

all of the absorbed energy is converted to potential energy

none of the energy is converted to kinetic energy

some of the absorbed energy is converted to potential energy and some is converted to kinetic energy

all of the absorbed energy is converted to kinetic energy

it spreads out through whatever container it is in

Explanation:

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

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.
