Test: Oxides & Allotrope of Oxygen - JAMB MCQ

Ozone is an allotrope of oxygen that consists of three oxygen atoms bonded together. It is formed in the upper atmosphere by the action of ultraviolet light on oxygen molecules.

Sulfur dioxide is a gaseous oxide produced by the burning of fossil fuels containing sulfur impurities. It reacts with water in the atmosphere to form sulfuric acid, which contributes to acid rain.

Hydrogen peroxide is an oxide of oxygen that is commonly used as a bleaching agent for hair and textiles. It also acts as a disinfectant due to its ability to kill bacteria and other microorganisms.

Carbon dioxide is a greenhouse gas that is released into the atmosphere through human activities such as burning fossil fuels. It traps heat from the sun, contributing to the greenhouse effect and global warming.

Carbon dioxide is commonly used in fire extinguishers because it is non-flammable and displaces oxygen, effectively smothering the fire by removing its oxygen supply.

Chlorine dioxide is an oxide of chlorine that has a sharp, pungent odor. It is often used as a disinfectant and has a distinctive smell similar to chlorine.

Nitrogen dioxide reacts with water vapor in the atmosphere to form nitric acid, contributing to the formation of acid rain. It is primarily produced through the combustion of fossil fuels.

Carbon monoxide is a commonly used reducing agent in metallurgical processes such as iron smelting. It reacts with metal oxides, reducing them to the pure metal form.

Sulfur dioxide has a pungent odor similar to that of rotten eggs. It is often produced by the burning of fossil fuels containing sulfur impurities and is associated with the smell of industrial pollution.

Carbon dioxide is essential for photosynthesis in plants. During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it along with sunlight and water to produce glucose and release oxygen.
