Good evening Dr. Behizadeh‚ I hope this email finds you well. I first would like to start out by saying that it was a privilege to be in your class last semester and I really learned a lot. I am writing you this email today because I have an escalating dilemma that I need some resources on. I recently received a job opportunity from a private school that I am currently working at‚ and things seemed to be going well. At the beginning of the school year I was receiving complaints about

The identification of acids and bases using a natural indicator Purpose: The purpose of this lab practice is to identify the pH of certain solutions and if they are acids or bases. Introduction: In chemistry‚ pH is a measure of the activity of the (solvated) hydrogen ion. p[H]‚ which measures the hydrogen ion concentration‚ is closely related to‚ and is often written as‚ pH. Depending on the pH solutions will be acids or bases. An acid is a chemical compound that dissociates in solution‚ releasing

As an eight-year-old pipsqueak who was regularly pitted against the twelve-year-old Goliaths of Albuquerque’s 12U tennis division‚ losing 0-6‚ 0-6 became a natural part of life‚ and I hated it. In fact‚ my tournament to-do list consisted of a dreadfully long car trip‚ suffering defeat upon defeat to another unnamed middle-school giant‚ and then drowning myself in a sea of tears while my dad lectured me about "unforced errors" on the trip home. As a result‚ I started to run away from tennis. I performed

INORGANIC CHEMISTRY 1 Lab Report on Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more electropositive

I assessed a patient with hip problem who came to the physical therapy department in the medical complex. After the clinical examination‚ i suspect there may be a Hip Labral tear that requires further investigations and testing to confirm the clinical diagnosis. i gave the patient a written note for his physician that suggests further diagnostic testing which may help to set an accurate diagnosis of the hip problem. His doctor wrote a letter back stating that the patient should have been at first
