I am going to assume that the reaction occurs in water since that is the easiest procedure (let me know if I am not supposed to make this assumption).
1) get 2 beakers, the chemicals for the reaction, DI water, and the catalyst.
2) equal volumes and amounts of the water was placed into the 2 beakers.
3) some of the catalyst was added to beaker the second beaker.
3) equal amounts of the chemicals for the reaction was placed into the 2 beakers.
4) the two reactions were compared to see how the un-catalyzed reaction in beaker 1 was effected by the introduction of a catalyst in beaker 2.
I hope this helps. Let me know in the comments if anything was unclear.
The correct answer that would best complete the given statement above is the term MOTION. The amount of heat in a substance depends on the motion of the molecules. Since the temperature is defined as the measure ofthe average kinetic energy of molecules. The higher the temperature, the faster the motion of the molecules would be. Hope this answer helps.
Answer:
Explanation:
1. First write the formula of each compound:
Sucrose : 
Water : 
Ethyl alcohol : 
Carbon dioxide : 
2. Write the equation with the reactants on the left and the products on the right:
3. Put the states of matter of each compound in the reaction, as the problem says:
aq = aqueous solution
g = gas
4. Balance each element.
The number of each atom must be the same on the left and on the right.
