4 Fe + 3 O2 → 2 Fe2O3
How many moles of Fe are needed to react with 1.00 moles of O2?
A FULL STEP EXPLANATION WILL BE APPRECIATED

We need 1.33 moles of Fe

Explanation:

Step 1: Data given

Number of moles O2 = 1.00 moles

Step 2: The balanced equation

4 Fe + 3 O2 → 2 Fe2O3

For 4 moles Fe we need 3 moles O2 to produce 2 moles Fe2O3

Step 3: Calculate moles Fe

For 4 moles Fe we need 3 moles O2 to produce 2 moles Fe2O3

For 1.00 moles O2 we need 4/3 * 1.00 = 1.33 moles Fe

There will be produced 0.67 moles Fe2O3

We need 1.33 moles of Fe

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
