Use this table below to identify the blocks from the diagram above Substance. Density

Water = 1.00 g/mL
Wood=. 0.53 g/cm³
Aluminum =. 2.64 g/cm³
Gold =. 19.29 g/cm³
Ice =. 0.92 g/cm³
Wax =. 0.80 g/cm³

if you mean hydrogen and oxygen then water is the product

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.
