During a class demonstration the potassium exploded. suggest what might have caused this to happen

Could’ve reacted with water as alkali metals are very reactive to water.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

It starts to rust i think
