2. A balloon is dunked into a tank of
cold water. How will this affect the
size of the balloon?

When an inflated balloon is placed in cold water, it shrinks. This happens because the air inside the balloon occupies a smaller volume when the temperature is decreased, thus causing the walls of the balloon to collapse. ... The decrease in temperature causes the air molecules to move more slowly, with less energy.

Explanation:

i would say b

explanation:

but i think i would need more information than that

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.
