Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Whether made in business‚ politics‚ science‚ or sports‚ most decisions are judged as either right or wrong‚ ethical or unethical. Regardless of what an individual believes about a particular action‚ if society judges it to be unethical or wrong‚ whether correctly or not‚ that judgment directly affects the organization’s ability to achieve its business goals. For this reason alone‚ it is important to understand business ethics and recognize ethical issues. social responsibility‚ an organization’s

The rate of a chemical reaction is the measure of change in concentration of the reactants of the change in concentration of the products per time. The rate of a chemical reaction is influenced by the concentration of the reactants‚ temperature‚ and the presence or absence of a catalyst. Through finding the time and concentrations of the reactants‚ it is possible to find the rate of reaction and k. To perform this experiment‚ you need two erlenmeyer flasks‚a timer‚ a LabQuest with a temperature

LAB REPORT FOR EXPERIMENT 3 COPPER CYCLE OLANREWAJU OYINDAMOLA TUESDAY 27TH February 2013 Abstract This experiment is based on copper‚ to synthesize some copper compound using Copper (II) nitrate solution to obtain copper metal at the end. Changes of copper complexes when various are added and filtering out the precipitate by using Buchner funnel for vacuum filtration .The experiment started with preparation of copper (II) hydroxide and addition of copper oxide then addition of droplets

Lab Report An enzyme is a protein that speeds up the rates of chemical reactions. They recognize‚ bind‚ and change specific reactants. They do not change so they can catalyze the same reaction again and again. Activation energy is the amount of energy needed in order to begin a chemical reaction. A Catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts are substances or a substance that configures another substance

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that

Using Le Chatelier’s Principle‚ we can determine the effects of temperature in both scenarios. First‚ imagine an endothermic reaction (heat is on the reactants side where the solid is). Increasing the temperature would result in stress on the reactants side from the additional heat. Le Châtelier’s Principle predicts
