Write the reaction that represents the combustion of C6H12O2. Determine the oxidation state of P in PO33-. Determine the oxidation state of C in CO3-2. What element is undergoing oxidation (if any) in the following reaction?CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g). Please explain and break down the necessary steps
a)
Write the reaction that represents the combustion of C6H12O2
C6H12O2 + O2 --> CO2+ H2O
Balance equation
C6H12O2 + 9O2 --> 6CO2+ 6H2O
b)
Determine the oxidation state of P in PO33-
O --> -2 (almost always O has -2 charge)
then
P + 3*(-2) = -3
P = -3 + 6 = +3
c)
Determine the oxidation state of C in CO3-2.
O --> -2 (almost always O will have a -2 charge)
The balance of charges:
C + 3(-2) = -2
C = -2+6 = +4
c)
What element is undergoing oxidation (if any) in the following reaction?CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g).
oxiddation ---> to lose electrons, or gain oxygens (by definition)
CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g).
Clearly, C is being oxidized
CH4 --> (C has -4 and H is +1 charged)
CO2 --> (C has +4 and O is -2 charged)
therefore
C --> -4 to + 4, its losing electrons, therefore oxidizing
