Balanced equation 2KNO3 --> 2KNO2 + O2
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
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.
The balanced equation for potassium oxide (K2O) reacting with carbonic acid (H2CO3) is: K2O + H2CO3 -> 2KOH + CO2
The reaction between KNO3 (potassium nitrate) and H2CO3 (carbonic acid) would not produce K2CO3 (potassium carbonate) and HNO3 (nitric acid). This is not a balanced chemical equation. The correct reaction between potassium nitrate and carbonic acid would involve a double displacement reaction, yielding nitric acid and potassium carbonate.
The chemical equation for the reaction between potassium oxide (K2O) and water (H2O) is: K2O + H2O → 2KOH In this reaction, potassium oxide reacts with water to form potassium hydroxide. The potassium oxide molecule (K2O) reacts with water (H2O) to produce two molecules of potassium hydroxide (2KOH).
The balanced equation is 2HCl + K2O -> H2O + 2KCl.
3H2C2O4 + 2K2MnO4 = 6CO2 + 2K2O + Mn2O3 + 3H2O
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.

2K + H2O ----> K2O + H2
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.
To balance the equation of potassium reacting with oxygen to form both potassium superoxide (KO2) and potassium oxide (K2O), you would write it as 4K + O2 -> 2KO2 and 4K + O2 -> 2K2O. This ensures that both sides of the equation have the same number of each type of atom.
A possible reaction is:Fe2O3 + 6 K = 3 K2O + 2 Fe
2KOH + H2SO3 --------> K2SO3 + 2H2O or K2O + SO2 ------> K2SO3
The word equation for the reaction that causes potassium to tarnish is: potassium (K) + oxygen (O2) → potassium oxide (K2O).
