question 11 (4 points)
according to the following equation, what is the oxidation number for iron in the product?
fe₂o₃(s) + 3co(g) → 2fe(l) + 3co₂(g)
a) -1
b) -2
c) 0
d) +1

Explanation:

Step1: Recall oxidation number rules

For an element in its elemental form (like Fe(l) here), the oxidation number is 0.

Step2: Identify the product's iron state

The product is Fe(l), which is iron in its elemental (metallic) state. By the rule of oxidation numbers for elemental substances, the oxidation number of an atom in an elemental form is 0.

Answer:

c) 0
