Answer to Question #214596 in General Chemistry for grace

Question

Assign an oxidation number to each element in the reaction.

CO(g) + 2H₂(g) → CH₃OH(g)

In CO, the oxidation number of C is , and that of O is . In H₂, the oxidation number of H is . In CH₃OH, the oxidation number of C is , that of O is , and that of H is . 

Answer 1

CO: C(+2); O(-2)

H2: H(0)

CH3OH: C(-2); H(+1); O(-2); H(+1)
