M+ e-    m-1is m oxidized or reduced?

Reduced

Explanation: Oxidation reaction is defined as the reaction in which a substance looses its electron. The oxidation state of the substance gets increased.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Given :

Thus as in the given reaction the oxidation state of the metal has decreased from 0 to-1, it is getting reduced.

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.
