Question

Iron metal reacts with oxygen gas you create iron three oxide FE 203 right the balanced reaction how many moles of iron three oxide are created from .20 moles of iron metal

Answer 1

1) balanced chemical equation.

`4\ Fe_((s))\ +\ 3\ O_(2)_((g))\ ->\ 2\ Fe_(2)O_(3)_((s))`

2) solve.

`=0.20\ mol\ Fe` ×
`(2\ mol\ Fe_(2)O_(3))/(4\ mol\ Fe)`

= 0.10 mol Fe₂O₃
