A 1-L sample contains 26g of casein (퐶8퐻12푂3푁2). If 18 g of bacterial cell tissue (퐶5퐻7푁푂2)is synthesized per 50 g of casein consumed, determine the amount of oxygen required to complete the oxidation of all the casein present in the sample to end products and cell tissue. The end products of the oxidation are carbon dioxide (퐶푂2), ammonia (푁퐻3

it is a good conductor

explanation:

it's all four options.

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.
