Answer:
Adhesion and cohesion
Explanation:
Capillary action refers to the ability of water to move in small-diameter or narrow tubes against the force of gravity. Water has a tendency to form hydrogen bonds with other water molecules.
Intermolecular hydrogen bonding allows the water molecules to stick together. This tendency of water molecules to stick together is called cohesion. Adhesion is the ability of the water to stick to other substances with polar or charged groups. As a consequence of cohesive and adhesive properties, water exhibits capillary action. When water moves through microscopic spaces present between the soil particles towards the roots, it is capillary action.
b. grow taller.
c. use alternation of generations.
d. make sugars for energy.
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.
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.
