October 1‚ 2013 Chemical Reactions of Copper Objective The objective of this lab is to convert copper (Cu0) “in a series of reactions to various compound containing copper as the Cu2+ species” (CHM111 Laboratory Manual) in order to prove the Law of the Conservation of Mass. Introduction In this experiment‚ we took a look at how copper (Cu0) reacts with different substances to get an end result where it is transformed back to its original state. There were five different reactions that involved

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

Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction

Chart 3.1: Velocity at 3 degrees Chart 3.2: Velocity at 6.3 degrees Chart 3.3: Velocity at 8.5 degrees Chart 3.4: Velocity at 90 degrees Discussion: The results that were observed from this lab helped prove what was hypothesized. As chart 1.4‚ 2.4 and 3.4 displayed the object dropped off of the 90 degree slope was the quickest to cross 200cm‚ had the highest velocity and the highest acceleration. This was because at 90 degrees the gravitational
