1) Consider the reaction when aqueous solutions of manganese(II) chloride and ammonium sulfide are combined. 2) Consider the reaction when aqueous solutions of lead(II) acetate and potassium hydroxide are combined.
3) Consider the reaction when aqueous solutions of aluminum acetate and nickel(II) bromide are combined.
The net ionic equation for this reaction is:.

sure what is it? ^w^

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

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.
