Mole ratio is the ratio between the amount in moles of any two compounds involved in a chemical reaction
3
the mole of Fe3O4 is 1 mole while that of Fe is 3 moles from the reacting equation below
Fe + 4 H2O ----> Fe3O4 + 4 H2
therefore the mole ratio of Fe3O4 to Fe is 1:3(answer A)
is aluminium oxide (also called aloxide, aloxite and alundum). It is neither acid nor base. It has amphoteric nature meaning it can act as an acid with bases and as a base with acids. It neutralises them to salts.
Answer:
1500 mmol.
Explanation:
Hello,
In this case, for such monovalent potassium species, we can verify that 1 mEq equals 1 mmol, therefore, the required solution is shown below:
Which means that also 1500 mmol of monovalent potassium ions are contained in the liter.
Regards.
