Question

What would be the effect on burning if the proportions of nitrogen and oxygen in air were reversed?

• A. The atmosphere would be explosive
• B. Oxygen reacting with the nitrogen to form poisonous nitrous oxides
• C. The digestion of protein would be affected
• D. All of the above

Answer 1

The correct option is D All of the above

if the proportion of oxygen were much greater, then it would be too reactive. Oxygen is a very reactive non-metallic element. If the proportion of oxygen were higher, then the atmosphere would be explosive; with the oxygen reacting with the nitrogen to form poisonous nitrous oxides.
