Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

This semester in English 101 has been very demanding for me. In previous years‚ I generally completed my writing assignments with ease and without having to put much thought or effort into them‚ but this year‚ I was required to work for many hours on each of my papers and to proofread them many times in order to receive a good grade. For example‚ I learned that if I wanted to reach my audience‚ I had to organize my paper in such a way that everyone could easily understand the organization and the

EXPERIMENT 1: TITLE: ISOMERISM AND KINETICS IN COORDINATION CHEMISTRY OBJECTIVE: 1. To prepare and study the kinetics of the interconversion of some of the isomers of a typical coordination compound. INTRODUCTION: Isomerism played a central role to establish the basic concept in coordination chemistry while reaction kinetics of coordination compound is known as the area of continuing intense research activity. The mechanism of the reactions of coordination compounds relevance

most often effective in producing photochemical change. The light required for a photochemical reaction may come from many sources. Giacomo Ciamician‚ regarded as the "father of organic photochemistry"‚ used sunlight for much of his research at the University of Bologna in the early 1900’s. One of the oldest and most studied photochemical reactions is the photoreduction of benzophenone (diphenyl ketone). It was discovered that solutions of benzophenone are unstable to light when certain solvents

The Importance of Camouflage By Biology 101 May‚ 29 2013 Introduction In life‚ we have heard the phrase “only the strongest will survive”‚ and undoubtedly‚ think of the strength of a lion or the ferociousness of a bear‚ but this is not always the case to being a dominant species in a community. In this lab‚ we will explore the theory of natural selection‚ or as Charles Darwin put it‚ “Survival of the fittest” (King et al‚ 1-14). Through this concept‚ we will come to the understanding

INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley between them. The organisms found on the south facing slope (SFS) slope of evolution canyon‚ which has harsher

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water
