experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure Exercise #1 Step #1: Convert %T (Table 1) to absorbance and prepare a Beer’s law plot using the data. Step #2:

The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would

October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

neither man would expect the effect these elements could have on modern science‚ namely rockets. But creating a rocket is just combining these two gases in a closed environment‚ and one spark. This lab exemplifies just that what happens when the gases H2 and O2 are chemically combined with a spark. In this lab‚ the objective was to see how far a pipette filled H2 and O2 could travel. One half a centimeter of H2O was added to keep the gases inside‚ and make sure that only these H2 and O2 where included

Do you think mistakes are only to make your life miserable? Mistakes are not always bad‚ they make us be stronger in the future and let better things occur in our lives. I always thought that by doing something bad‚ it will make us regret our lives and our past; that it will make us be ashamed of ourselves but I now realize that it shouldn’t be that way. Mistakes are like levels in a game‚ you may be able to pass them without getting harmed and they will teach you something new so next time it comes

I did this lab to find out the differences between chemical and physical changes. I also did this lab to learn the signs that would indicate the chemical reactions and physical changes. I needed to learn the odor change‚ color change‚ bubbles or gas‚ irreversible‚ temperature changes and finger prints. By the end of the lab‚ my goal was to be able to didtinguish easily the difference between chemical and physical changes. Question #1 answer. 1. Gas. 2. Dissolved in water. 3
