KO2 (potassium super oxide) is used in space and submarines because it :a)absorbs CO2 and increases O2 contentsb)eliminates moisture and increases CO contentsc)absorbs CO2onlyd)produces ozoneCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Answer

Potassium Superoxide (KO2) is an oxygen (O2) generator, a dehumidifier (removes water content) and remover of carbon dioxide (CO2). For this reason, it is used in breathing apparatus used in spacecrafts, space suits, submarines and by miners and fire-fighters. Potassium Superoxide reacts fast, to give rise to above reactions.It has a yellow, solid structure and may be produced by burning molten potassium, in an oxygen filled environment

following reaction

4KO2+2CO2----->2K2CO3+3O2

Answer

A)

Answer

Benefits of KO2 (potassium super oxide) in space and submarines:

Eliminates moisture:
- KO2 reacts with moisture in the air, producing potassium hydroxide, which helps in eliminating moisture from the surroundings.
- In space and submarines, excess moisture can lead to corrosion of equipment and discomfort for the crew, so KO2 plays a crucial role in maintaining a dry environment.

Increases CO content:
- By eliminating moisture, KO2 helps in increasing the carbon monoxide (CO) content in the surroundings.
- This is important in submarines where CO is used for various processes and in space where CO can be used for propulsion.

Other uses:
- KO2 also has the ability to absorb carbon dioxide (CO2) and produce oxygen (O2) through a chemical reaction.
- This feature is especially useful in space missions where oxygen generation is vital for the survival of astronauts.

Conclusion:
Overall, the use of KO2 in space and submarines is crucial for maintaining a dry environment, increasing CO content, and producing oxygen, making it an essential component for life support systems in these environments.
