Non-metals don't react with water but the non-metal oxides do react with water and they produce acids. One example is chlorine gas (chlorine oxide) reacts with clouds (water) to form acids which come down as acid rain.

Non-metals and their reaction with water

Introduction:
Non-metals are a group of elements that do not possess the typical characteristics of metals. They are poor conductors of heat and electricity, have low melting and boiling points, and are generally brittle. When non-metals react with water, the products of the reaction depend on the specific non-metal involved.

Explanation:

1. Hydrogen gas is formed:
When non-metals like hydrogen and oxygen react with water, they can form hydrogen gas. This is because hydrogen is already present in water in the form of H2O molecules. When hydrogen reacts with water, it can displace the hydrogen atoms in the water molecule, resulting in the formation of hydrogen gas (H2). This reaction is commonly observed in the electrolysis of water, where an electric current is passed through water to separate hydrogen and oxygen gases.

2. Carbon dioxide gas is formed:
Non-metals like carbon can also react with water to form carbon dioxide gas (CO2). This reaction occurs when carbon compounds, such as organic acids, dissolve in water. The carbon atoms in these compounds can combine with oxygen from the water molecule, resulting in the release of carbon dioxide gas. This reaction is commonly seen when carbon-containing substances, such as coal or wood, are burned in the presence of water vapor.

3. Non-metals do not react with water:
However, it is important to note that not all non-metals react with water. Some non-metals, such as noble gases like helium and neon, are generally unreactive and do not readily undergo chemical reactions with water or other substances. These gases are stable and do not easily form compounds with other elements. Therefore, the correct answer to the given question is option 'C' - non-metals do not react with water.

Conclusion:
In summary, the reaction of non-metals with water depends on the specific non-metal involved. While some non-metals like hydrogen can react with water to form hydrogen gas, and others like carbon can react to form carbon dioxide gas, there are also non-metals that do not react with water at all. It is important to consider the properties and reactivity of individual non-metals when studying their reactions with water or other substances.

Non-metals are electronegative are unable to break the bond between H and O in water. The non-metals cannot reduce hydrogen by donating electrons. Thus non metals do not react with water.
