Organic Chemistry: CHP 225 Thomas Hsieh Experiment 2: Boiling Points o Date experiment was performed: September 16‚ 2011 o Objective: To determine the boiling point of organic compounds such as tert-butyl alcohol‚ sec-butyl alcohol‚ n-butyl alcohol‚ and an unknown. o Principle: Boiling point is the temperature at which gas and liquid phases coexist in equilibrium. At this temperature‚ the vaporization rate and the condensation rate are equal. The liquid and vapor reach a state of dynamic

turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a certain concentration of road salt will have an affect on a specific type of plant. Also to see what changes will occur like the color

Measuring Cup Water Timer Tongs Observation/Question: Do all paper towels have the same absorbency? Are more expensive paper towels more absorbent? Hypothesis: I think more expensive paper towels are more absorbent than less expensive paper towels. Experiment: Controls: Same amount of water for each paper towel; same size paper towel used; the same surface used in each attempt; process to determine the amount of water left; the water will be left on the paper towel for the same amount of time; test

Risk Taking Experiment A. There are many risks in life one must take. I had several options to explore for this experiment such as going on a drop roller coaster‚ sky diving‚ and killing insects. I thought that sky diving would be fun‚ but I am not old enough to do because the minimum age requirement was eighteen years old. I also explored the idea of killing insects especially spiders which I hate the most‚ but I thought going on a drop roller coaster would be more interesting. B. I chose the

An experiment by FACUNDO LOPEZ MENTOS GEYSER CARBONATED DRINKS AND MENTOS PROBLEM STATEMENT: WHAT IS THE EFFECT OF MENTOS ON CARBONATED DRINKS? BACKGROUND INFORMATION: The soda contain sweeteners (sugar or artificial sweeteners) flavoring‚ water and preservatives. Carbon dioxide (CO2) gas is added to the soda trough a high pressure process that causes the gas to dissolve into the liquid‚ when the soda is opened the gas is relieved
