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() ► 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.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

wher is the rest of the question
