Describe how to make pure dry crystals of magnesium chloride from magnesium carbonate and a dilute acid.
In your method you should name the apparatus and reagents you plan to use.

we will take a known volume of hydrochloric acid in a conical flask and add excess insoluble magnesium carbonate. they will react to produce soluble magnesium chloride and carbon dioxide gas. we will filter out the excess magnesium carbonate using filter paper and collect the filtrate which is the magnesium chloride solution. next, heat the solution till the point of saturation and allow it to cool. filter the solution to collect the magnesium chloride crystals and allow them to dry.

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.
