Can you tell me if I got this single displacement question correct

[From: ] [author: ] [Date: 12-10-19] [Hit: ]
and is it balanced?Also, what would the net ionic equation be? Can you explain how you figured it out also? Thank you, thank you,......
2Al(s)+3FeO(s)----->Al2O3(aq)+3Fe(s)

Is that correct? Is it in the right order, are the symbols right, and is it balanced?

Also, what would the net ionic equation be? Can you explain how you figured it out also? Thank you, thank you, thank you!

Al2O3(s) otherwise all OK.
Net ionic equation:
2Al + 3Fe2+ ---> 2Al3+ + 3Fe

This is a redox reaction where the Al is oxidised (Al atoms lose electrons):
2Al ---> 2Al3+ + 6e-
and the iron ions are reduced (iron ions gain electrons):
3Fe2+ + 6e- ---> 3Fe
The oxide ions (O2-) remain unchanged throughout so they do not appeer in the net equation.

Yes your equation is correctly balanced as shown. This is the very energetic thermite reaction, makes molten iron in seconds.

The net ionic reacftion shows only the reactants and products which change charge during the reaction, so the aluminum on the left went from zero charge as an elemental metal to a plus 3 charge on the right when two aluminum atoms combined with three oxygen atoms. The iron in the iron 2 oxide on the left went to an uncombined fre+3e elemental iron on the right with zero charge.

2Al (zero charge) plus 3 Fe (plus 6 total charge) yields 2Al (plus 6 total charge) plus 3 Fe (zero charge total) Balanced net ionic equation. Oxygen is left out because its charge on both sides of the equation is -2 per ion. Your balanced equation is correct.

yes

Al(0) + Fe+3 -------> Al+3 + Fe(0)
