I need help with this question!!

A. 15

Explanation:

From the equation we see that 6 water particles are used to make 1 particle of the hexose.

That means, that to make 1 mole of the hexose, we need 6 moles of water (as a mole is an unit of count of particles).

To make 2.5moles of the hexose, we need 2.5*6 moles of water, so 15 moles of water.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

it means there are 3 atoms of oxygen
