Platinum is used to catalyze the hydrogenation of ethylene: h2(g)+ch2ch2(g)−⟶pt(s)ch3ch3(g) chlorofluorocarbons (cfcs) catalyze the conversion of ozone (o3) to oxygen gas (o2): 2o3(g)−⟶cfc(g)3o2(g) magnesium catalyzes the disproportionation of hydrogen peroxide to produce water and oxygen: 2h2o2(aq)−⟶mg(s)2h2o(l)+o2(g) what type of catalysts are platinum, cfcs, and magnesium under these conditions? drag the appropriate items to their respective bins.

Catalysts lower the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction. Catalysts are classified as homogeneous ( same state as the reactants ) or heterogeneous (different state as the reactants). Platinum would be a heterogeneous catalyst. CFCs would be a homogeneous catalyst. Magnesium would be a heterogeneous catalyst.

Ithink it’s 3 as the answer.

Variables,control,conclusion and finally scientific theory
