Magnesium - aluminium alloys are widely used in circraft
construction. one particular alloy contains 70.0% al and
30.0% mg. how many grams of halg) are produced in
the reaction of 0.710g samples of this alloy with excess
heleg?
2 alig + 6hcl(aq) – 2 acc( 3 lags + 3h2 lg)
mg(s) + 2hcl(aq) - mg cl2 lag) + h2 lg)

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.
