Question

In the following balanced chemical equation, what does the subscript number after oxygen in iron(III) oxide mean?

2 Fe2O3 + 3 C → 4 Fe + 3 CO2
A. 3 atoms of oxygen in iron (III) oxide
B. 3 molecules of iron (III) oxide
C. 3 molecules of oxygen in iron (III) oxide
D. 3 atoms of iron (III) oxide

Answer 1

The correct answer is A. 3 atoms of oxygen in iron (III) oxide. subscript number after oxygen in iron(III) oxide represents the number of oxygen atoms in the compound. the chemical equation represents the number of oxygen atoms present in each molecule of iron(III) oxide.

Step-by-step explanation:

The subscript number after oxygen in iron(III) oxide in the chemical equation represents the number of oxygen atoms present in each molecule of iron(III) oxide. the number of oxygen atoms in the compound. the chemical equation represents the number of oxygen atoms present in each molecule. Therefore, the correct answer is A. 3 atoms of oxygen in iron (III) oxide.

The correct answer is A. 3 atoms of oxygen in iron (III) oxide. subscript number after oxygen in iron(III) oxide represents the number of oxygen atoms in the compound. the chemical equation represents the number of oxygen atoms present in each molecule of iron(III) oxide.
