What is the oxidation of Fe in Fe2O3

Chemistry
1 answer:
Inessa05 [86]3 years ago
4 0

Answer/ explanation :

The oxidation number of Fe

In Fe2O3

To solve this problem,

The oxidation number of O is -2

Oxidation number of Fe is x

Note that there are 2moles of Fe and 3moles of O

2 Fe + (-2 * 3) = 0

2 Fe + (-6) = 0

2 Fe - 6 = 0

2 Fe = 6

Fe = 6/2

Fe = +3

Therefore, the oxidation number of Fe is +3

The sign is very important, either - or +

Sheena has a lump of sodium, a lump of potassium and a lump of lithium, but they’ve got mixed up and she doesn’t know which one
Arada [10]

Answer:

Explanation:

Just saw your request regarding answering this so here it is:

All of them belong of Group 1 in periodic table and thus are highly reactive! Pattern of reactivity for Group 1 (Alkali metals) increases as you move down the group as their radius keeps increasing and thus electrons can be easily lost. Thus, to ID the lumps, Sheena should look at their reactivity and she should get the following trend:

Most reactive: Potassium (K)

Intermediate: Sodium (Na)

Least reactive: Lithium (Li)

Hope it helps!
