Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we will

A Look at “Positive Affect and Health” As Sheldon Cohen and Sarah D. Pressman first note‚ academic literature on the subject of chronic negative thoughts and affective styles is plentiful‚ focusing on the increase risk of disease. But in the paper “Positive Affect and Health‚” 2007‚ Cohen and Pressman attempt to combine literature on positive thoughts and affective style with their own research and study into the subject. Predominantly‚ the authors seek to highlight the correlation between an individual’s

Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is a fermenter they will use the sugars to make ATP. If the bacteria

Bio Lab Report Title: Gram-Negative and Gram-Positive contamination in yogurt. Introduction: There is bacteria that is beneficial and harmful in the human. Yogurt was choosed to be the best example that contains this bacteria. What happens to be the difference between these two types of bacteria‚ and how are they harmful? The bacteria is considered “Gram-Negative‚” and the substance is considered contaminated when there is more negative bacteria than positive bacteria. This will prove or disapprove

Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes. Materials known as acids when dissolved
