Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.

Conclusion to Motion Lab Kerreon Wright 3rd Period Ms. Gislason The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible

Jonathan Nebelsick VO2 Max Tests Conclusion Submaximal VO2 tests are extremely useful for determining estimated VO2 maxes for a subject for a variety of reasons. VO2 max measures the maximum amount of oxygen that can be used by a person undergoing intense physical exertion. VO2 max is considered the best test of cardiovascular fitness and aerobic endurance. If a person can utilize more oxygen‚ then they are able to use that oxygen as a final electron acceptor to make ATP through aerobic metabolism

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

In conclusion‚ after conducting the lab‚ the emergent properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate
