What is the mole ratio of fe304 to fe?

Chemistry
1 answer:
serg [7]3 years ago
4 0
Answer: 1:3

Explanation:

1) To state the mole ratio of a product and a reactant we need the chemical equation that shows the reaction.

2) In the case of Fe3O4 and Fe, the chemical equation is:

<span>              Fe+H2O → Fe3O4+H2.

3) Now, you balance the equation, which will give you the coefficients of each reactant and product of the chemical reaction:
</span>
<span>              3Fe+4H2O → Fe3O4+4H2

4) From that the mole ratios are:

              3 mol Fe : 4 mol 4H2O : 1 mol Fe3O4 : 4 mol H2.

5) The question requires you to find the mole ratio for Fe3O4 to Fe. Tha is:

            1 mole Fe3O4 : 3 mole Fe

So, the answer is 1:3

How many moles of Au2S3 is required to form 56 grams of H2S at STP?
Law Incorporation [45]

Answer:

0.55 mol Au₂S₃

Explanation:

Normally, we would need a balanced equation with masses, moles, and molar masses, but we can get by with a partial equation, if the S atoms are balanced.

1. Gather all the information in one place:

M_r:                          34.08

          Au₂S₃ + … ⟶ 3H₂S + …  

m/g:                             56  

2. Calculate the moles of H₂S

Moles of H₂S = 56 g H₂S × (34.08 g H₂S/1 mol H₂S)

                      = 1.64 mol H₂S

3. Calculate the moles of Au₂S₃

The molar ratio is 1 mol Au₂S₃/3 mol H₂S.

Moles of Au₂S₃ = 1.64 mol H₂S × (1 mol Au₂S₃/3 mol H₂S)

                         = 0.55 mol Au₂S₃

Which of the following statements about trends in solubility is accurate?
Kipish [7]

"The solubility of gases decreases as temperature rises" statements about trends in solubility is accurate.

<u>Option: D</u>

<u>Explanation:</u>

A substance's solubility is the quantity of that component that is needed at a defined degree of temperature to produce a saturated solution in any set quantity of solvent. Some compounds like hydrochloric acid, ammonia, etc  have solubility that reduces with rising temperature. They are both standard-pressure gases.

When heating a solvent with a gas absorbed in it, both the solvent and the solute spike in the kinetic energy.When the gaseous solute's kinetic energy rises, the molecules have a higher propensity to overcome the solvent molecules' connection and migrate to the gas phase. Thus, a gas's solubility reduces with rising temperature.
