Answer:

ratio is 5Fe2+/1KMnO4

Explanation:

You can find the ratio using the coefficients of the known and unknown variables. This will shift the answer for your calculations so make sure to include it. without the mole ratio step, you can not compare 2 molecules or elements.

3Fe+4H2O(yields) Fe3O4+4H2. What is the mole ratio of Fe3O4 to Fe?
WINSTONCH [101]

<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

Mole ratio is defined as the ratio between the stoichiometric coefficients of the molecules present in the chemical reaction.

For the given balanced chemical equation:

3Fe+4H_2O\rightarrow Fe_3O_4+4H_2

By Stoichiometry of the reaction:

3 moles of iron metal reacts with 4 moles of water to produce 1 mole of iron oxide and 4 moles of hydrogen gas.

The mole ratio of Fe_3O_4:Fe=1:3

Hence, the correct answer is Option A.
