Answer 1

answer is 2, 3, and 6

Step-by-step explanation:

cuz it is

Answer 2

Step-by-step explanation:

Fe has 2 Fe ions making up Fe2O3

There are 3 oxygen ions making up Fe2O3

There are 3*2 = 6 hydrogen ions making up 3H2

If you haven't been told what an ion is, you can use atoms in your answer, but it is not entirely correct.
