    • 2 Pages

    The purpose of Experiment 36 is to identify the anions present in an unknown solution based on the chemical reactions with various chlorides. In this experiment‚ Pb2+ was present in the unknown solution‚ while the presence Hg22+ is in doubt‚ and Ag+ is absent. To begin‚ the first part of the experiment involved analyzing the results from the experiment with the solution with equal volumes of AgNO3‚ Pb(NO3)2‚ and Hg2(NO3)2. Based on the results and observations obtained from the tests with the stock

    The purpose of my experiment is to determine which temperature will allow Luminol to glow at its greatest capacity. My hypothesis is that the glow will illuminate for the longest time in a cold temperature because it will take longer to dissolve. I also predict that in the warmer temperature‚ the glow will be at it’s brightest. Luminol is a chemical‚ which exhibits chemiluminescence with a blue glow. It is a solid that is soluble in most polar solvents‚ but insoluble in water. Luminol is widely

    Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can

    Extended Experimental Investigation | May 28 2013 | Drosophila melanogaster lab experiment Question: How do the dominant or recessive genes in particular traits in a cross between a male and female Drosophila determine the traits of its offspring? Aim: to establish whether characteristics produced from the offspring of a drosophila cross are recessive or dominant traits. Hypothesis: If certain phenotypes are expressed in the offspring from the cross of certain Drosophila‚ then the determination

    Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life.  These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids.  These are monomers and they link together into long chains that form polymers.  Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

    Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

    on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚ then they will regenerate stronger and faster. This is important because it could lead to faster regeneration for the animal and lead to bigger things such as finding a way to incorporate this to human regeneration. Many experiments have been researched

    Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic compounds produced by geochemical processes‚ but that most of these original compounds were used up billions

    Title: You Light Up My Life Purpose: To determine how different environmental conditions affect a plants starch levels. Hypotheses: 1. If the plant that is in absence of CO2 and is kept in a closed environment‚ then it will have a starch level of 1 because the plant is missing CO2‚ which it needs to complete the photosynthesis process. 2. If the plant is in a closed environment‚ then the plant will have a starch level of 3 because it has all the environmental conditions it needs. 3. If the plant
