The chemical equation for the reaction between potassium and oxygen is:
4K + O2 -> 2K2O
An equation refers to a reaction, not an individual compound. The formula of potassium oxide is K2O. If you mean the equation for its formation from the elements, it is 4K + O2 --> 2K2O.
2 KNO3 ↔ 2 KNO2 + O2
Potassium plus Water gives Potassium Hydroxide plus Hydrogen
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
chlorine plus potassium bromide gives bromine plus potassium chloride. Here is the symbol equation, but remember that the numbers AFTER the symbols should be subscripts. Cl2 + 2KBr = Br2 + 2KCl

2 KNO3 ↔ 2 KNO2 + O2
This reaction is:2 KClO3 = 3 O2 + 2 KCl
Potassium + Chlorine --> Potassium Chloride (potassium plus chlorine arrow potassium chloride)
Potassium plus Water gives Potassium Hydroxide plus Hydrogen
Potassium nitrate is too stable and so is silver for these two species to react. There is thus no balanced equation.
The balanced equation for this reaction is: 2 KClO3 -> KClO4 + KCl
The equation is:2 KOH + H2SO4 = K2SO4 + 2 H2O
chlorine plus potassium bromide gives bromine plus potassium chloride. Here is the symbol equation, but remember that the numbers AFTER the symbols should be subscripts. Cl2 + 2KBr = Br2 + 2KCl
Octane + oxygen ---> carbon dioxide + water Lulu
The word equation for copper reacting with oxygen is: copper + oxygen → copper oxide.
