We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the

Then tip the cylinder to about 45 degrees then put sample into it slowly‚ DON’T spill any water or have to restart. Make sure no air bubbles are clinging. Then take down final volume of water cylinder. 6. Dump the water out‚ then dry sample off. 7. Repeat this over with the other metal samples. * Hypothesis: * My hypothesis is that even though I will find the densities and names of the unknown metals its not going to be accurate because some water will spill out.

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

Psychotherapy Timeline Ronda A Harrison Tenth Century- Ca. 900 - The concept of mental health was first born. It was also known as mental hygiene and was introduced by Ahmed ibn Sahl al-Balkhi. He believed that mental illness could have both psychological and physiological causes. Also in the same time frame Al-Razi Rhazes recognized the concept of psychotherapy. Eighteenth Century – Between 1770 and 1774 Johann Joseph Gassner and Frank Mesmer introduced the practice of hypnotherapy. Mesmer believed

Health Level 7 For my presentation I chose the topic HL7. After doing the bit of research on the internet I found what HL7 was? The question that I will address is what does the name HL7 means‚ and why and how it was organized. What is HL7? Health Level Seven is one of the several American National Standards Institutes (ANSI) to give credit for standards Developing Organizations (SDOS) operating in the healthcare place.

Utilizing the Lab Results PS2200 - Criminal Investigation Unit 04 Assignment 01 As the lead homicide investigator for this case I had recently learned that the crime lab has concluded that the finger print that was recovered belonged to the boyfriend‚ they were from a piece of notebook paper found under the body of the victim. Interviews are conducted in criminal cases for the purpose of gathering information from people who have‚ or may have‚ knowledge needed in the investigation. (Swanson
