PLEASE THIS IS URGENT!! 1.) Write 2 points of difference between water molecule and hydrogen molecule.

2.) Differentiate between homogeneous and heterogeneous mixture.

1.) Write 2 points of difference between water molecule and hydrogen molecule.

• Water molecule associates through hydrogen bonding while hydrogen molecule associates through weak vanderwaal's forces of attraction.

• Water molecule is heavier with greater molecular mass [ 18 grams ] than hydrogen molecule [ 2 grams ].

2.) Differentiate between homogeneous and heterogeneous mixture.

• Homogeneous mixture is a mixture where molecules combine uniformly and adhesive forces are greater than cohesive forces while heterogeneous mixture is a mixture where molecules are non-uniformly combined and cohesive forces are greater than adhesive forces.

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 .
