When hydrogen peroxide (h2o2) is added to potassium iodide (ki) solution, the hydrogen peroxide decomposes into water (h2o) and oxygen (o2). the chemical equation for the decomposition reaction is: 2h2o2—> 2h2o + o2. what is the role of the potassium iodide in this reaction? a. reactant. b. product. c. precipitate. d. catalyst.

Why does an evaporating liquid cool down according to the kinetic molecular theory? heat is required to evaporate a liquid. heat is lost through elastic collisions. the highest velocity molecules are lost. heat must be dissipated to break the liquid bonds.
