when non-metals react with water, then _________.

Options

A. Hydrogen gas is formed
B. Carbon dioxide gas is formed
C. Non-metals do not react with water
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Non-Metals:** Non-metals are elements that generally lack the characteristics of metals. They are poor conductors of heat and electricity and can exist in various states (solid, liquid, gas) at room temperature.

2. **Reactivity of Non-Metals with Water:** When considering the reaction of non-metals with water, it is important to note that most non-metals do not react with water. This is a key characteristic of non-metals.

3. **Exceptions - Non-Metallic Oxides:** Although non-metals themselves do not react with water, their oxides can. Non-metallic oxides, when dissolved in water, typically form acids. For example, sulfur dioxide (SO₂) reacts with water to form sulfurous acid (H₂SO₃).

4. **Conclusion:** Based on the above points, the correct statement is that non-metals do not react with water. Therefore, the answer to the question is that when non-metals react with water, then they do not react.

5. **Final Answer:** Non-metals do not react with water.
