I think it would have 10 neutrons. Hope this helps :)
Yes, it depends on the size of the ball and the weight. If it's heavy and big then it'll affect how far it rolls, if it's small and has no weight then it won't really move as much
Answer:
Chemical equation: NH₃(g) + O₂(g) → NO(g) + H₂O(l).
Oxidation reaction: N⁻³ → N⁺² + 5e⁻ /×4.
Reduction reaction: O₂⁰ + 4e⁻ → 2O⁻² /×5.
Oxidation reaction: 4N⁻³ → 4N⁺² + 20e⁻.
Reduction reaction: 5O₂⁰ + 20e⁻ → 10O⁻² /×5.
Balanced chemical equation: 4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(l).
Ammonia (NH₃) reacts with oxygen (O₂) and form nitrogen(II) oxide (NO) and water (H₂O). Catalyst is this reaction is platinum (Pt).
This is combustion reaction.
