FAQs on Reaction of Non Metals with Oxygen- Materials : Metals & Non-Metals

Question 1

1. What happens when non-metals react with oxygen?

Accepted Answer

Ans. When non-metals react with oxygen, they form oxides. These oxides can be solids, liquids, or gases depending on the non-metal involved in the reaction. For example, carbon reacts with oxygen to form carbon dioxide gas, sulfur reacts with oxygen to form sulfur dioxide gas, and phosphorus reacts with oxygen to form phosphorus pentoxide solid.

Question 2

2. Why do non-metals react with oxygen?

Accepted Answer

Ans. Non-metals react with oxygen because they have a tendency to gain electrons in order to achieve a stable electron configuration. Oxygen is highly electronegative, meaning it has a strong attraction for electrons. Non-metals have fewer electrons in their outermost energy level, so they react with oxygen to gain electrons and achieve a stable electron configuration.

Question 3

3. What are some common examples of non-metals reacting with oxygen?

Accepted Answer

Ans. Some common examples of non-metals reacting with oxygen include the combustion of carbon, sulfur, and phosphorus. When carbon burns in the presence of oxygen, it forms carbon dioxide gas. When sulfur burns in the presence of oxygen, it forms sulfur dioxide gas. When phosphorus burns in the presence of oxygen, it forms phosphorus pentoxide solid.

Question 4

4. How does the reaction of non-metals with oxygen affect the physical state of the product?

Accepted Answer

Ans. The reaction of non-metals with oxygen can result in the formation of solids, liquids, or gases. For example, the reaction of carbon with oxygen produces carbon dioxide gas. The reaction of sulfur with oxygen produces sulfur dioxide gas. The reaction of phosphorus with oxygen produces phosphorus pentoxide solid. The physical state of the product depends on the non-metal involved in the reaction and the conditions under which the reaction occurs.

Question 5

5. What are some applications of the reaction of non-metals with oxygen?

Accepted Answer

Ans. The reaction of non-metals with oxygen has several applications. For example, the combustion of carbon in the presence of oxygen is used in various heating and energy production processes. Sulfur dioxide gas, formed by the reaction of sulfur with oxygen, is used in the production of sulfuric acid. Phosphorus pentoxide solid, formed by the reaction of phosphorus with oxygen, is used as a dehydrating agent in organic synthesis.
