An element is a substance that can’t be broken down into simpler substances by chemical means, a compound is when two or more elements are combined chemically to form something new, and a mixture is when two or more substances are combined but not chemically.
Maybe lol, because if one is an in and another is a neutral, it makes two balls, then afterwards, you'll need a big stick!

Hope this helps!
Answer:
The correct option is;
The reaction pathway for the trials is different
Explanation:
The effect of a catalyst in a chemical reaction is to increase the rate of a reaction by changing the pathway or mechanism of the reaction and/or to lower the transition state's energy thereby lowering the activation energy of the reaction
The pathway of the reaction is changed by the catalyst by the formation of intermediate compounds by the catalyst which require lower activation energy to form the products than the original non-catalyzed reactants. In the process the catalyst is regenerated, thereby, not taking part in the reaction.
