How much heat is needed to raise the temperature of 5.28 gal of water from 25.0°C to 88.0°C (1 gal = 3.785 L)(1L =

1000g)?

A 5270 kj

B 1390 kJ

C 7360 kj

D 2090 kJ

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.

b.false that your answer

the answer is symmetrical : )
