A student measured the volume of water to be 18.5 ml; the actual volume was 17.5 ml. What was the % deviation

+5.7%

Explanation:

18.5mL/17.5mL = 1.057 = 105.7% - 100% = 5.7%

Since the measured volume was higher, it is PLUS 5.7%

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.

diaria maybe go see a doctor about that
