Question

In which of the following reactions is carbon oxidized? (Select all that apply)

1. Combustion of octane (a major component of gasoline):
   C $_8$ H $_{18}$ (l) + 25/2 O $_2$ (g) ⇄ 8 CO $_2$ (g) + 9 H $_2$ O (g)

2. Pacification of carbon monoxide (occurs in a car's catalytic converter):
   CO (g) + 1/2 O $_2$ (g) ⇄ CO $_2$ (g)

3. Chlorination of methane (an industrial process):
   CH $_4$ (g) + 4 Cl $_2$ (g) ⇄ CCl $_4$ (l) + 4 HCl (g)

Answer 1

solution: & combustion of Octane: che, = Bet9 M. Inthi's reaction carbon is oxidized leg removal of one drogen occur - Pacification of carbon monoxide: In this reaction carbon is oxidized iet addition, al oxygen occur. 107 ^ u do -) chlovination of Methane : 1 44 (2) + 4 (7) 449) + 440g) In this reaction casson is oxidized. iet removal of Hydrogen occur
