The reaction of potassium with oxygen: When potassium ( K ) is heated strongly with oxygen ( O 2 ) , then it forms potassium superoxide ( KO 2 ) as a product.

Potassium oxide (K2O) is an ionic compound of potassium and oxygen. It is a base. This pale yellow solid is the simplest oxide of potassium.

The balanced equation for the reaction of potassium with oxygen is: 2 K + O 2 → 2 K 2 O . Step by step solution. 01. Write down the unbalanced equation. First, ...
