The fact that ice is less dense than water is related to the fact that .
Group of answer choices

the molecules are held to each other by covalent bonding

ice has a structure that is held together by hydrogen bonds

the structure of ice is much less orderly than that of water

ice has a structure in which water molecules are arranged randomly

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

1 is the answer to this problem

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.
