4K+O2=2K2O

K2O+H2O=2KOH

Answer 2

Chemical Reactions

The question asks to describe the chemical reactions to convert oxygen (O2) to potassium hydroxide (KOH) by going through the intermediate compounds potassium oxide (K2O) and potassium hydroxide (KOH).

The reactions are:

1. Oxygen (O2) reacts with potassium (K) to form potassium oxide (K2O):

`K + 1/2O2 → K2O`

This reaction involves oxidation, where oxygen oxidizes potassium by taking electrons from it.

2. Potassium oxide (K2O) reacts with water (H2O) to form potassium hydroxide (KOH) and hydrogen gas (H2):

`K2O + H2O → KOH + 1/2H2`

This reaction is an acid-base reaction, where the acidic potassium oxide reacts with the basic water molecule to form potassium hydroxide and hydrogen gas.

So in summary, the overall chemical reaction is:

`K + 1/2O2 + H2O → KOH + 1/2H2`

Oxygen is first used to oxidize potassium to potassium oxide, which then reacts with water to yield the final product, potassium hydroxide.
