Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

Chemical Bonding Lab Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types—ionic and covalent. Ionic bonds result when one or more electrons from one atom or group of atoms is transferred to another atom. Positive and negative ions are created through the transfer. In covalent compounds no electrons are transferred; instead electrons are shared by the bonded atoms. The physical properties of a substance‚ such as melting point
