Since the Grignard reagent can easily react with water‚ all glassware including the 25 ml round bottom flask‚ magnetic stir bar‚ 3 and 5 ml conical vial‚ 50 mL Erlenmeyer flask‚ claisen adapter‚ drying tube and 5 glass pasteur pipets were first added to a 250mL beaker and placed in the oven for 30 minutes. After the completion of the thirty minutes‚ 0.150 g of shiny magnesium turnings and a stir bar was first added to the round bottom flask and the claisen adapter along with the drying tube packed

Harris Homeostasis Lab Report Objective: This experiment was conducted to determine how homeostasis maintains the bodies balance after doing a workout. Homeostasis is the maintaining of a balanced condition in the body despite changing external conditions or demands on the body. In this lab the participant was to execute an exercise to determine if homeostasis would maintain an stable heart beat and breathing rate. Materials: There was only a few materials used in this lab: -Stopwatch

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

Lung Capacity in this lab‚ I learned about lung capacity and CO2 production. Lung capacity simply means the maximum amount of air you can take into your lungs. Lung capacity and CO2 production closely relate to the respiratory system. The respiratory system is the system in which oxygen goes into your body and carbon dioxide comes out; In short it’s breathing. The structures involved in the respiratory system are mouth/nose‚ mucus/cilia‚ pharynx‚ larynx‚ bronchi‚ bronchioles‚ alveoli‚ pleura‚ and

Meal Worm Cellular Respiration Experiment Introduction Cellular respiration provides energy to all living organisms by collecting energy from food molecules. The cell then rearranges complex molecules to simpler molecules and uses that energy to make a molecule that stores energy called adenosine triphosphate also known as ATP. Cellular respiration can occur with or without oxygen. When it occurs without oxygen‚ it is called anaerobic respiration. There are very few organisms that can get
