final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore

Taki Simadiris p1 Brierly Post-lab a. If you did not wash all of the Calcium Carbonate out of the beaker and into the filter during step 5‚ would your percent yield be larger or smaller? If you do not wash all of the Calcium Carbonate out‚ then the percent yield would be smaller because there is enough calcium carbonate left in the beaker that would have attributed to the final yield. b. If you used tap water instead of DI water what do you think would happen? Why? If you used tap water‚ the coffee

The Genetics of Fast Plants Kristin Phillips Dr. Orlando April 4‚ 2014 Abstract The experiment that was being completed was the genetics of plants using Fast Plants. The purpose of this project was to understand Mendel’s concept of a Dihybrid by performing similar crosses and calculated the phenotypes that are displayed. This project was conducted over many weeks by planting F1 seed and waiting for them to grow then cross-pollinating the F1 plants to produce the F2 seeds. Next students

Micro Biology Lab Gram Staining Lab Report Purpose The purpose of this lab was to experiment with a staining technique called Gram Staining. Gram Stains is used to identify and classify bacteria‚ it is a differential stain that allows you to classify bacteria as either gram-positive or gram-negative. The foloowing is a breif summerary of the gram staining procedure. Apply the primary stain Apply Mordant Apply decolorizing agent Apply the secondary stain Bacteria that

effect of citric and buffered lactic acids on the flavour of hard-boiled sweets and the effect of acids on various flavours in high temperature applications. Introduction Materials and Methods An amount of water‚ sugar and glucose syrup of 30g‚ 100g and 70g were weighed respectively into a stainless steel pot. The mixture was then heated and removed immediately from the induction cooker after reaching the desired temperature of 145˚C. Flavours of 0.51g and acid of 1.20g was added immediately afterwards

Cells rely on processes such as cellular respiration and fermentation in order to produce ATP through a series of steps. There are two different types of fermentation: lactic acid fermentation in humans and alcohol fermentation in yeast and bacteria. All of these processes synthesize ATP‚ however‚ unlike respiration‚ both types of fermentation occur when oxygen is not present. In addition‚ each process undergoes a critical first

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration
