Write the net ionic equation for the following reactions:?

Question

1.) Iron fillings added to copper (II) sulfate in solution

2.) Aluminum metal reacts with oxygen to form aluminum (III) oxide

Answer 1

1) Fe(s) +Cu^2+(aq) --> Fe^2+(aq) + Cu(s) Single replacement, redox reaction where iron is oxidized and copper is reduced

2) 2Al(s)+(3/2)O2(g)-->Al2O3(s)
redox reaction, oxygen is reduced (neutral to -2) and aluminum is oxidized (neutral to +3)
