Question

Fe + HNO3 = Fe(NO3)2 + N + H2O

Answer 1

Ответ:

Fe + 6HNO3 → Fe(NO3)3 + 3NO2 + 3H2O (если кислота концентрированная)

Fe+4HNO3=Fe(NO3)3+NO+2H2O(если разбавленная)

Объяснение:

Answer 2

The chemical equation you provided is not balanced. Let's balance it using the method of balancing chemical equations:

Fe + HNO3 = Fe(NO3)2 + N2 + H2O

Balancing the equation:

1. Start with the atoms that appear in only one reactant and one product: Fe + HNO3 = Fe(NO3)2 + N2 + H2O

2. Balance the nitrogen (N) atoms: Fe + HNO3 = Fe(NO3)2 + N2 + H2O

Since there are two nitrogen atoms on the right side but only one on the left side, we need to balance the nitrogen atoms by putting a coefficient of 2 in front of HNO3:

Fe + 2HNO3 = Fe(NO3)2 + N2 + H2O

3. Balance the hydrogen (H) atoms: Fe + 2HNO3 = Fe(NO3)2 + N2 + 3H2O

4. Balance the oxygen (O) atoms: Fe + 2HNO3 = Fe(NO3)2 + N2 + 3H2O

Since there are 6 oxygen atoms on the right side but only 2 on the left side, we need to balance the oxygen atoms by putting a coefficient of 2 in front of Fe(NO3)2:

Fe + 2HNO3 = 2Fe(NO3)2 + N2 + 3H2O

Now the equation is balanced, and the correct chemical equation is:

Iron (Fe) + Nitric acid (HNO3) = Iron(II) nitrate (Fe(NO3)2) + Nitrogen gas (N2) + Water (H2O)
