Observing and deciphering Chemical Changes Purpose The purpose of this experiment is to observe reactions of chemicals that can be found in consumer products. Through observation‚ students should be able to interpret the chemical reactions and determine some characteristics‚ such as pH and solubility. Method 1. Pipets containing chemicals will be opened using scissors to snip the end and each pipet will be placed in a well of a 24-well plate. The scissors must be washed between each pipet. 2

Abstract: Using genes that control development makes it possible to identify mutants that alter development. Anterior –Posterior axis formation is controlled by protein gradients in the early embryo development. Bicoid and nanos mRNAs are both maternally provided and are localized to opposite poles of the embryo (Springfield‚ 2016). Bicoid proteins are concentrated at the anterior end and nanos proteins concentration is highest at the posterior end of the embryo (Springfield‚ 2016). The combination

Lamb and Stephonya Williams EXPERIMENT TITLE: Oxidation: Cyclohexanone from Cyclohexanol by Hypochlorite Oxidation and Adipic Acid from Cyclohexanone DATE: 4/18/2014 INTRODUCTION: In experiment 4‚ alcohol is oxidized to a ketone with household bleach. The product is then isolated by steam distillation and is extracted into the distillate with ether. After the removal of ether‚ it leaves the product cyclohexanone. In experiment 6‚ cyclohexanone is oxidized by potassium permanganate. Manganese

this chemical reaction does occur‚ then the material does in fact contain Sodium Bicarbonate. B. All Purpose Cleaner with Bleach – the reaction remained blue from the Bromthymol Blue‚ and then turned clear again after about a minute. Windex Window Cleaner – the reaction remained a dark blue color. Bleach – the Bromthymol Blue chemical remained at the top of the bleach‚ not mixing‚ then after a minute turned clear again. From my observation‚ most household chemicals are bases‚ since the Bromthymol

soap advertisements depicting the ‘before and after’ transformations were not only selling soap or bleach but a dominant ideology symbolizing imperial progress. In an ad for Chlorinol Soda Bleach‚ three boys are pictured in a soda box sailing in the ocean. The image contains two black boys pictured proudly holding boxes of Chlorinol. The third boy undoubtedly has already used the Chlorinol bleach because his skin is a distinct white. The sail of soda box reads ‘We are Going to Use “Chlorinol”

hair. When used regularly‚ the juice will eventually lighten hair strands and give the effect of highlights. It does not turn dark hair to immediately bleach blonde‚ but gives the hair some life. For a big change the “most famous hair bleach is hydrogen peroxide of peroxide blonde fame. Unlike sunlight and lemon juice‚ peroxide is an oxidizing bleach‚ and its effects are less easily undone" (4). Hydrogen Peroxide lightens hair by stripping an oxygen molecule from the hair. If you put hydrogen peroxide
