A 0.692 g sample of glucose, C6H12O6 , is burned in a constant- volume calorimeter. The temperature rises from 21.70 0C to 25.22 0C. The calorimeter contains 575 g of water, and the bomb has a heat capacity of 650 J/K. Determine ∆r E per mol of glucose

gas

explanation:

smoke is the matter of a gas

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.
