For the compounds (or ion) shown, show the correct name, the total number of valence electrons, and Electron Dot Structure.  Show these results to your instructor so that he can check them.  Make correct models for each of the compounds shown, and check these with your instructor.

Exp 7: Specific Heat of a Metal

In this experiment, you will perform experiments on energy and matter.  One of the experiments you will do is to determine the heat of fusion of water.  You will do this experiment by taking ice and adding it to water in a calorimeter.  After the ice has melted, you will determine the amount of heat required for the melting by solving the thermodynamic heat equation (q=SHxMx”T).

Exp 8: Chemical Reactions and Balanced Equations

For this experiment, the difficult part is not doing the experiment.  The difficulty comes with the manipulation of the data.  For this reason, I am listing the calculations that you need to do.  After doing this experiment, you be able to determine the correct formula for the oxide of magnesium and the correct formula for the hydrate of magnesium sulfate. Be certain to use the same balance for all determinations, and make certain the scale is "zeroed" before doing any weighing.

Exp 11: Gas Laws

Print the protocol in pdf format by clicking on the URL link above.

In this lab we will examine two of the most important gas laws: Boyle's Law and Charles' Law. These two gas laws describe the relationships between Pressure and Volume (Boyle's Law) and Temperature and Volume (Charles' Law).

Exp 12: Solutions and Solubility

In this experiment, you will perform experiments designed to understand solutions and factors which affect solubility.  You will also do some acid-base experiments to determine the pH of different solutions, and examine how buffers work.

Exp 13: Acids and Bases

For this experiment, you will examine pH using a dye indicator that you will make yourself from red cabbage, which changes color at different pH values.  You will then determine the approximate pH of several household chemicals using your dye indicator and standardized buffers at different pH's.
