How to balance it, step by step
- Count the atoms of each element on both sides, as written.
- Start with the biggest formula, N₂: put 1 in front of it.
- N: 2 on the left. Put 2 in front of NO.
- O: 2 on the right. Put 1 in front of O₂ (1 × 2 = 2).
- Check: N 2 = 2, O 2 = 2. Balanced.
What happens
It is a combination reaction: two or more substances join to form a single product. Nitrogen and oxygen combine to nitric oxide only at very high temperatures, as in lightning or a car engine.
Nitrogen and oxygen: quick answers
What is the balanced equation for nitrogen and oxygen?
N₂(g) + O₂(g) → 2 NO(g). The coefficients are 1, 1 and 2. Each side then has 2 N and 2 O.
What type of reaction is nitrogen and oxygen?
It is a combination reaction: two or more substances join to form a single product. Nitrogen and oxygen combine to nitric oxide only at very high temperatures, as in lightning or a car engine.
How do you balance N₂ + O₂ → NO?
Start with the biggest formula, N₂: put 1 in front of it. N: 2 on the left. Put 2 in front of NO. O: 2 on the right. Put 1 in front of O₂ (1 × 2 = 2). Never change a subscript, because that would change the substance.
