Q6 (Medium): What happens when oxygen reacts with magnesium and sulphur. What are the main differences in the nature of products formed?

Answer:
We have studied that metals and non-metals form different types of oxides when they react with oxygen . This is why the products have different natures.

  • Magnesium + Oxygen → Magnesium oxide ( basic )
  • Sulphur + Oxygen → Sulphur dioxide ( acidic )
  • Metal oxides are basic in nature
  • Non-metal oxides are acidic in nature
