Answer:

The correct answer is the first option: 4 mol Fe , 3 mol O2

Explanation:

Hello!

Let's solve this!

The reaction is:

4Fe + 3O2 ---> 2Fe2O3

This reads that every 4 moles of iron consumed, we need 3 moles of oxygen and when they react, we get 2 moles of Fe2O3.

Let's analyze each of the options:

4 mol Fe

3 mol O2: this is correct since it tells us how much iron and how much oxygen we need.

2 mol Fe2O3

4 mol Fe: it is not correct because it does not tell us anything about oxygen.

4 mol Fe

2 mol Fe2O3: it is not correct because it does not tell us anything about oxygen.

3 mol O2

2 mol Fe2O3: it is not correct because, although it says of oxygen, it does not relate it to iron.

We conclude that the correct answer is the first option: 4 mol Fe

3 mol O2

Answer:

Option A says we have 4 moles of Fe for each 3 moles O2

This is correct For 3 moles of O2 consumed, we need 4 moles of Fe to be reacted

Explanation:

Step 1: Data given

Step 2: The balanced equation

4Fe + 3O2 → 2Fe2O3

Step 3: Calculate the mol ratio

For 3 moles O2 we'll have 4 moles Fe

Option A says we have 4 moles of Fe for each 3 moles O2

This is correct For 3 moles of O2 consumed, we need 4 moles of Fe to be reacted

Option b says we have 2 mole Fe2O3 for each 4 moles Fe

This doesnt say anything about O2. So doesn't apply for this question.

Option C says we have 4 moles of Fe for each 2 moles Fe2O3

This is the same as option B, so doesn't apply for this question.

Option D says for each 3 moles of O2 we have 2 Fe2O3

This is true, but doesn't say anything about Fe so doesn't apply here.

If 14.3 moles of H2O2 is decomposed, how many grams of oxygen gas are produced?
Studentka2010 [4]
The balanced chemical reaction would be as follows:

2H2O2 = 2H2O + O2

We are given the amount of the peroxide that decomposes. Using this as the starting point for the calculations, we can determine the amount of O2 produced. We do as follows:

14.3 mol H2O2 ( 1 mol O2 / 2 mol H2O2 ) = 7.15 mol O2 produced
