In the previous lab we used different types of reagents to help determine if the presence of proteins‚ starches‚ and reducing sugars were present in the solutions we were provided with. The purpose of the lab was to allow us to have the opportunity to view the positive and negative reactions of the solutions we used‚ also to understand what that meant. The reagents we used allow us to detect whether or not there was a reducing sugar‚ starch‚ or protein present in the solutions. From what I knew previous

Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Snell’s Law to calculate

The age of excess is upon humanity. Long gone are the days where one must scavenge or hunt for food‚ protect themselves and their family or tribe from beasts and the elements‚ and perpetually realize one’s impermanence; their existence at the mercy of all threats found in the harsh wilderness of days past. Today‚ one lifts themselves into their hefty metal transportation device and traverse a complex network of terraformed pathways all the way to a sustenance station‚ where food is not a possibility

Discussion Our results indicate that the presence of iron increases the rate of the peroxidase’s activity‚ judging from the increase in absorbance with increasing amount of iron. This result supports our hypothesis that the iron acts as a cofactor in peroxidase’s activity and results in the faster rate of the reaction. Also‚ we assumed that the more we put iron in the solutions‚ the faster the rate is. This assumption is also supported by the results that higher concentration of iron cofactors shows

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

Arianna Montoya Osmosis and Diffusion Lab Report Background Information: Diffusion involves the movement of solute particles across a selectively permeable membrane from higher to lower concentrations. A selectively permeable membrane allows only some thing to go through. Water and oxygen are examples of molecules that are able to go through the membrane

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable
