Explanation:

Carbon dioxide

1)Carbon dioxide is used by plants for photosynthesis.

2)Carbon dioxide is an odorless (at very low concentrations), colorless gas that is stable at room temperature. Living creatures produce carbon dioxide as a waste product of respiration, which is then utilized by plants to form food by photosynthesis. Carbon dioxide also has numerous industrial and commercial uses—ranging from firefighting to electronic equipment manufacture.

3)Industrial Applications. Carbon dioxide gas is used in industries to produce chemicals and as feedstock. According to “IPCC Special Report on Carbon Dioxide Capture and Storage,” carbon dioxide gas is involved in the production of refrigeration systems, welding systems, water treatment processes (to stabilize the pH of water) and carbonated beverages. It is also used in the metals industry to enhance the hardness of casting molds and as a soldering agent. Carbon dioxide is found in various fire extinguishers and prevents oxygen from further fueling a fire. Carbon dioxide-based fire extinguishers effectively manage electrical fires and those caused by solvents, fuels and oils.

4)Chemical and Pharmaceutical Applications. Carbon dioxide gas is used to make urea (used as a fertilizer and in automobile systems and medicine), methanol, inorganic and organic carbonates, polyurethanes and sodium salicylate. Carbon dioxide is combined with epoxides to create plastics and polymers. It is used for water treatment; to keep food cool (as dry ice); and to cool, pressurize and purge equipment.

5)Electronic Applications. Carbon dioxide gas is used in the electronics industry for circuit board assembly, to clean surfaces and in the manufacture of semiconductor devices.

6)Oil Industry. Carbon dioxide gas is used in enhanced oil recovery (EOR). EOR is a class of techniques for increasing the quantity of extracted crude oil from oil fields. Carbon dioxide is injected under high pressure into an oil reservoir, which pushes the oil through pipes and up to the surface of the ground. Carbon dioxide gas injection aids oil recovery and reduces the viscosity of recovered oil.

7)Fire extinguisher. Carbon dioxide will not burn or support combustion. Air with a carbon dioxide content of more than 10% will extinguish an open flame, and, if breathed, can be life-threatening. Such concentrations may build up in silos, digestion chambers, wells, sewers and the like. Caution must be exercised when entering these types of confined spaces.

8)Carbon dioxide plays a major role as a component of the carbon cycle in which carbon is exchanged between the atmosphere, the terrestrial biosphere (which includes freshwater systems and soil), the oceans, and sediments (including fossil fuels). These interactions are complex and widespread. They undoubtedly can be, and are, influenced by many types of human activities, but the extent to which humans have impacted these processes, and will impact them in the future, remains the subject of much research and debates

9)Health Care Uses: Carbon dioxide is used as an additive to oxygen for medical use as a respiration stimulant.

Oxygen

Oxygen gas forms the compounds with nearly all the elements except the inert gases , It is compressed in iron cylinders to be used in mechanical ventilation for the patients who suffer from breathing difficulties and it is used during surgeries .

Oxygen gas is used by the mountaineers at high latitudes during climbing as oxygen gas is heavier than the air , so its percentage decreases when we rise above the Earth’s surface .

Oxygen gas is used by underwater divers during diving , and the astronauts use it during walking in the space , Oxygen masks are used to ease various medical disorders , like hypoxemia , asthma , the heartand the vascular diseases .

Oxygen gas is used in the formation of the waterthat is composed of oxygen combines with hydrogen , It is used to kill bacteria causing gangrene ( as it is poisonous for them ) and it is used to treat carbon monoxide poisoning as well .

Oxygen gas combines with acetylene gas to produce oxy-acetylene flame which is used for cutting , welding and melting of metals as its temperature rises to 3500 degree Celsius .

Oxygen gas is used in the production of iron and steel in the blast furnaces using hot oxygen air, It also burns off carbon impurities , Even in mines , it is employed as a part of explosives for blasting rocks .

Oxygen gas forms the ozone layerinthe atomosphere that protects the Earth from harmful radiations that come from the Sun , Ozone molecule is composed of three oxygen atoms ( O3 ) .

Oxygen gas is used in the manufacture of nitric acid , sulfuric acid , other compounds , and acids , Ozone is used in different chemical reactions to improve the rate of reaction and ensure the fullest possible oxidation of the compounds .
