When potassium metal is placed in water, a large amount of energy is released as potassium hydroxide and hydrogen gas are produced in the reaction 2K (s) + 2H2O (l) → 2KOH (aq) + H2 (g). Your lab partner says this is a redox reaction and a combustion reaction. Do you agree? Defend your answer by explaining whether or not it meets the requirements of each type of reaction.

It's a redox reaction since k has been oxidised and h has been reduced. i doubt it's a combustion rxn since the end products should be C0₂ and H₂0
