?Fe(2+)+?NO3(-)+H(+)==》No+Fe(3+)+H2O
What's the balanced equation?
?Fe^2+ + 4H^+ + [NO3]^- ==> ?Fe^3+ + 2H2O + NO
You determine the number for Fe^2+ and Fe^3+ by balancing the charge on the left with the charge on the right.
Hint: Try 1 and if that doesn't work try 2 and if that doesn't work try ........ etc.
To balance the given chemical equation: Fe(2+) + NO3(-) + H(+) → NO + Fe(3+) + H2O, we need to ensure that the number of atoms of each element on both sides of the equation is the same. Here is how to balance it step by step:
1. Start by balancing the atoms which appear only once on each side of the equation. In this case, it's the Iron (Fe) atoms. There is one Fe atom on each side, so the equation becomes: Fe(2+) + NO3(-) + H(+) → NO + Fe(3+) + H2O.
2. Next, balance the hydrogen (H) atoms by adding H+ ions to the left-hand side of the equation. In this case, there are 3 H atoms on the right side, so the equation becomes: Fe(2+) + NO3(-) + 3H(+) → NO + Fe(3+) + H2O.
3. Now, let's balance the oxygen (O) atoms. We have 3 oxygen atoms in the nitrate ion (NO3-) on the left side, but only 1 oxygen atom in water (H2O) on the right side. To balance the oxygens, we need to add 2 water molecules on the right side: Fe(2+) + NO3(-) + 3H(+) → NO + Fe(3+) + 2H2O.
4. Finally, all atoms are balanced except for the nitrogen (N) atom. There is one nitrogen atom in NO3(-) on the left side, and there is one nitrogen atom in NO on the right side. So the nitrogen atoms are already balanced.
The final balanced equation is: Fe(2+) + NO3(-) + 3H(+) → NO + Fe(3+) + 2H2O.
