In an ion with an unknown charge, the total mass of all the electrons was determined to be 1.640 x g, the total mass of its protons was 4.015 x g, and the total mass of its neutrons was 4.690 x g. What is the identity, charge, and mass number of this ion? Electron one mass = 9.109 x Proton one mass = 1.673 x Neutron one mass = 1.675 x

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.
