Fe + O2 ==> Fe2O3 need a 4 in front of Fe and a 3 in front of O2, as in the following:4Fe + 3O2 ===> 2Fe2O3
The reaction is:
2 FeCl2 + Cl2 = 2 FeCl3
Based upon balancing the ( NO3 ) ions , I put a 2 by the Al(NO3)2 and a 3 by the Fe(NO3)3.
Then I put a 3 next to FeCl3 and a 2 next to AlCl3 to balance the Fe atoms and the Cl atoms .
So I have :
2 Al(NO3)3 + 3 FeCl2 -------> 3 Fe(NO3)2 + 2 AlCl3
So I have :
Item Left Side Right Side
Al 2 2
(NO3) 6 6
Fe 3 3
Cl 6 6
O 18 18
N 6 6
1. Put a 2 by the Al(NO3)3 .
2. Put a 3 by the Fe(NO3)2 .
3. Put a 2 by the AlCl3 .
4. Put a 3 by the FeCl2 .
5. Each side has 18 oxygen atoms.
6. Each side has 6 nitrogen atoms.
7. Each side has 2 aluminum atoms.
Add 2 to FeCl3 first.Then a 3 to Cl2 ,now a two to Fe.Now it is balanced.
The reaction is:
2 FeCl2 + Cl2 = 2 FeCl3
The chemical equation is:
2 Fe + 3 Cl2 = 2 FeCl3
Fe + O2 ==> Fe2O3 need a 4 in front of Fe and a 3 in front of O2, as in the following:4Fe + 3O2 ===> 2Fe2O3
2Fe + 3Cl2 --> 2FeCl3
This equation is 2 Fe + 3 Cl2 -> 2 FeCl3.
2NF3 --> N2 + 3F2
the answer is 2 apex
It is balanced.
3AgNO3 + FeCl3 ---> 3AgCl + Fe(NO3)3
This equation is 2 Fe + 3 Cl2 -> 2 FeCl3.
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.

The coefficient of O2 is 5.The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
FeCl3 + H2O4-2 +Zn

The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
FeCl2 + CoCl3
Skeleton: FeCl3 + NaOH ----> Fe(OH)3 + NaCl Balanced: FeCl3 + 3NaOH ----> Fe(OH)3 + 3NaCl :) good luck!
2NF3 --> N2 + 3F2
