4NH3(g) + 3O2(g)= 2N2(g)+ 6H2O(l)
Interesting but what's the question?
The given chemical equation represents the reaction between ammonia (NH3) gas and oxygen (O2) gas to produce nitrogen (N2) gas and liquid water (H2O). This is a balanced chemical equation, which means that the number of atoms of each element is the same on both sides of the equation.
To determine the balanced equation, we need to make sure that the number of atoms of each element is the same on both sides. Here's how you can balance this equation step by step:
1. Start by counting the number of atoms on each side of the equation. On the left side, we have:
- 1 nitrogen (N) atom (from NH3)
- 3 hydrogen (H) atoms (from NH3)
- 3 oxygen (O) atoms (from O2)
2. On the right side, we have:
- 2 nitrogen (N) atoms (from N2)
- 12 hydrogen (H) atoms (from 6 H2O)
- 3 oxygen (O) atoms (from 3 O2)
3. Since the number of nitrogen (N) atoms is not the same on both sides, we need to adjust the coefficients in front of the compounds. To balance the nitrogen atoms, we place a coefficient of 2 in front of NH3 and N2. The equation now becomes:
2NH3(g) + 3O2(g) = 2N2(g) + 6H2O(l)
4. Next, let's balance the hydrogen (H) atoms. On the left side, we have 6 hydrogen (H) atoms from 2 NH3 molecules. On the right side, we have 12 hydrogen (H) atoms from 6 H2O molecules. The equation is now balanced in terms of hydrogen (H).
5. Finally, let's check if the equation is balanced in terms of oxygen (O). On the left side, we have 3 oxygen (O) atoms from 3 O2 molecules. On the right side, we have 3 oxygen (O) atoms contributed by the 6 water (H2O) molecules. The equation is balanced in terms of oxygen (O).
The balanced chemical equation for the given reaction is:
2 NH3(g) + 3 O2(g) = 2 N2(g) + 6 H2O(l)
