Indica que masa de cinc ha sido necesaria añadir a una disilucion de acido clorihidrico, sabiendo que se han obtenido 30 litros de hidrogeno medidas a 760 mmHg y 20 °C según la reacción Zn +HCl -> ZnCl2 -> H2. Dato Zn= 65,5u

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 .
