2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |

Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose

Lab 6 Experiment 2 1. It is important that bass caught and marked are returned to the lake unharmed because if they are harmed them they are less likely to be caught again or they may end up dying if they are returned harmed. 2. I don’t this type of population would be easier to count directly because I don’t think it would be possible to catch all of the bass in the population to conduct this experiment. 3. I think that sample size is relative to population density and will positively

Chemical Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent

PRACTICAL 6: OSMOREGULATION AND EXCRETION Introduction Many animals need to control the water content of their body because the concentration of their body fluids is different to that of their environment. The process by which the amount of water and concentration of soluble ions in the body are regulated is called osmoregulation. In most cases the organs which are responsible for osmoregulation are also involved in the excretion of metabolic waste products. In this practical you will

Course Name and Number: CIS 333 LAB#6 Instructor Name: Professor West Lab Due Date: 19 May 2013 1. What is the difference between a risk analysis (RA) and a business impact analysis (BIA)? Risk analysis is often identifying the potential threats and the associated vulnerabilities to the organizations .Risk analysis doesn’t view the organization from the mission critical Business Process point of view. More over BIA perceives the organization from the impact that is going to occur for an organization

Kya Wolf Prof. Ranta May/05/2014 Lab 6 My opinion about the code of silence is that it was in their blood to keep silent. In Southie they felt a sense of security and that was a feeling that you didn’t get in too many communities those days. For good or bad they always had that sense of neighborhood‚ they shared struggle‚ they shared identity. That’s something that most people don’t have or appreciate. Yet it was also a world that inspired fierce loyalty and a rock-solid sense

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

Analysis of a Chemical Reaction Purpose: To observe a chemical reaction and to use qualitative and quantitative evidence to identify this reaction from among four possibilities. Hypothesis: I think the result is going to produce water. I think this is going to happen because there is hydrogen and oxygen inNaHCO3. Materials: -Test tube clamp - 150 mm test tubes (2) - burner - retort stand - clay triangle - iron ring - crucible Procedure: Part A: 1. Add 0.5 g of NaHCO3
