Question

Given the following equation...

Fe + H2SO4 → Fe2(SO4)3 + H2
What is the charge (oxidation number) of Fe in Fe2(SO4)3 in 334 g of Fe2(SO4)3 ? (use atomic masses rounded to the nearest whole number.)

Answer 1

+3

Step-by-step explanation:

Answer 2

The charge is +3

Step-by-step explanation:

In Fe₂(SO₄)₃ the global charge is 0.

As we know, the sulfate ion, SO₄, has a charge of -2, as there are 3 SO₄ ions in the molecule, the global charge is -2*3 = -6. To solve for the charge of Fe we can use:

2Fe - 6 = 0

2Fe = +6

Fe = +3

The charge of the Fe of Fe₂(SO₄)₃ is +3
