Calculate the total amount of heat given off by burning something in 600 grams of water (specific heat of water is 4184 J/Kg K and the temperature change was 11.6 degrees Celcius)

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.

it's c (engineer's do their work with mechanical stuff not on any living being)
