Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

Title: The Recipe for the Highest Bouncing Super Ball Name: Date: November 14‚ 2013 Question: How much borax is needed from 1g to 5g to produce a super ball with the highest bounce from the height of 1.5m? Hypothesis: If 2 g of borax is used to make the super ball then it will produce the highest bounce because 2 g will make the appropriate number of bonds without producing a ball that is too soft or too hard to bounce. Materials: Paper cup Beaker Graduated cylinder Stir stick Pencil
