_ N2 + _ O2 → _ NO
The balanced chemical equation for the reaction is:
2 N2 + O2 → 2 NO
To balance the chemical equation N2 + O2 → NO, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
1. Start by counting the number of nitrogen atoms (N) on each side of the equation:
- There are 2 nitrogen atoms on the left side and only 1 on the right side.
2. To balance the nitrogen atoms, we need to place a coefficient in front of the NO on the right side of the equation. We'll use 2 as the coefficient:
N2 + O2 → 2NO
3. Next, count the number of oxygen atoms (O) on each side of the equation:
- There are 2 oxygen atoms on the left side and 2 oxygen atoms from the NO on the right side.
4. The oxygen atoms are already balanced.
The final balanced equation is:
N2 + O2 → 2NO
To balance the equation N2 + O2 → 2NO, we first need to count the number of atoms for each element on both sides of the equation.
On the left-hand side, we have 2 nitrogen atoms (N2) and 2 oxygen atoms (O2). On the right-hand side, we have 2 nitrogen atoms (2NO). However, the oxygen is only present as a diatomic molecule, O2, on the left-hand side.
To balance the oxygen atoms, we need to have the same number of oxygen atoms on both sides. Since there are 2 oxygen atoms in O2, we will need to put a coefficient of 2 in front of NO on the right-hand side: N2 + O2 → 2NO.
Now, we have balanced the number of oxygen atoms, but we need to check if the equation is balanced for nitrogen. On the left-hand side, we have 2 nitrogen atoms (N2), and on the right-hand side, we have 2 nitrogen atoms (2NO). As both sides have 2 nitrogen atoms, the equation is balanced.
Therefore, the balanced equation is: N2 + O2 → 2NO.
