Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases
Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits.
Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.

Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:
A + B + X --> C
A + B + Y --> C
A + B + Z --> C
The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.
I hope it helps, Regards.
Answer:
Prepare three test tubes containing reactant A.
Prepare three test tubes containing reactant B.
Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns.
Time the reaction until bubbling stops.
The unknown that causes the reaction to occur the quickest is the catalyst.
