Question

1) 'k' is used in breathing equipment for mountaineers. Why?​

Answer 1

Explanation:

Direct combustion in dry air converts pottasium to potassium superoxide, KO2, which is used in respiratory/breathing equipment because it liberates oxygen and removes carbon dioxide and water vapour. The pottasium (k+)and oxygen ions(O2-)combine readily to form an unstable compound. When one breathes  the gas through the respiratory equipment, it  helps  accelerate the rate at which oxygen dissociates with pottasium  to form water vapour and carbon(iv)oxide

Answer 2

Potassium(K) is used in breathing equipment for mountaineers because it absorbs carbon dioxide and increases oxygen levels at high altitudes.

• Potassium reduces carbon dioxide and water vapor and liberates oxygen. That's why it is used in breathing equipment.

• The potassium and oxygen combine to form an unstable compound KO2.

• Potassium is used in space suits, Mining work, fire fighting, etc.

• Potassium is a potent oxidizer some times it can produce volatile reaction when combining with a variety of compounds.
