Two scientists are investigating the properties of water. In one experiment, they notice that water breaks down to hydrogen and oxygen gas during a chemical reaction. Which of the following does this experiment demonstrate A. it demonstrates that a water molecule consists of two hydrogen atoms and one oxygen atom.

B. it demonstrates that water consists of atoms

C. it demonstrates that water is a compound

D. it demonstrates that water is an element

A

Explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the objects have the same charge.
