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

1) balanced chemical equation.

2) solve.

×

= 0.10 mol Fe₂O₃

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
