Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium

IB Chemistry Experiment 4 Composition of a Post-1983 Penny Lab Report Background: Through the use of percent composition one can easily find out how much of a certain element is in a compound or an item such as a post-1983 penny. The experiment will be using HCl a strong acid to dissolve all the zinc inside the outer copper shell. The reaction follows as such; Zn+2HCLZnCl2+H2‚ but there will be no reaction with copper. The portion that will be measured is the mass of copper left after all of

Human ECG Abstract The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore‚ the equipment used in the experiment will show the functions in the right and left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction

Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

Antibiotic Lab Report By: Sierra Toll Hour: 6 Title: The effects of antibiotics on the growth of Escherichia Coli Problem: How do antibiotics affect the growth of E coli? Hypothesis: If Penicillin is applied to the bacteria‚ then the zone of inhibition will be larger. Background: The purpose of this lab was to see how effective a certain antibiotic is to kill E coli. The lab tested three antibiotics‚ Penicillin‚ Erythromycin‚ and Neomycin. The zone of inhibition‚ which is the amount of space

December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil
