Answer 3

The chemical equation you provided appears to be incomplete and lacks proper balancing. To write a balanced chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's complete and balance the equation for the reaction between ammonium dichromate [(NH4)2Cr2O7] and nitrogen gas (N2) to form chromium(III) oxide (Cr2O3) and water (H2O).

The balanced chemical equation for this reaction is:

(NH4)2Cr2O7 + N2 → Cr2O3 + 4 H2O + N2

Now, let's balance the equation by adjusting the coefficients to ensure that the number of atoms of each element is the same on both sides:

1. Balance the nitrogen atoms (N): On the left side, there are 2 nitrogen atoms in (NH4)2Cr2O7, and on the right side, there are 1 nitrogen atom in N2. To balance nitrogen, we can put a coefficient of 2 in front of N2 on the right side:

(NH4)2Cr2O7 + 2 N2 → Cr2O3 + 4 H2O + 2 N2

2. Balance the hydrogen atoms (H): On the right side, there are 4 hydrogen atoms in 4 H2O. To balance hydrogen, we need 4 ammonium ions on the left side (4 NH4). Therefore, put a coefficient of 4 in front of (NH4)2Cr2O7 on the left side:

4 (NH4)2Cr2O7 + 2 N2 → Cr2O3 + 4 H2O + 2 N2

3. Balance the chromium atoms (Cr): On the left side, there are 2 chromium atoms in (NH4)2Cr2O7, and on the right side, there are 2 chromium atoms in Cr2O3. Chromium is already balanced.

Now, the equation is balanced with the same number of each type of atom on both sides:

4 (NH4)2Cr2O7 + 2 N2 → Cr2O3 + 4 H2O + 2 N2

This balanced equation represents the reaction between ammonium dichromate and nitrogen gas to produce chromium(III) oxide and water. Please note that this reaction is not typically observed under normal conditions and may require specific experimental conditions to occur.
