<span> B. produces as much energy as cell respiration. i am pretty sure that is the answer</span>
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

Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:
Where, the molar mass of each element are:
Calculating the molar mass of the compound, we have:
Now, calculating what is the mass of 6.78 of , we have:
So, there are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
Have a nice day!
To arrange these elements according to the atomic radius (smallest to largest) would be:
Be, Mg, Ca, Sr, Ba
