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

study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing

In the story Silver Water‚ Amy Bloom’s main character Rose who is mentally ill and had her first psychotic breakdown when she was 15. Her sister Violet wants everyone to know that she was normal before the illness happened. Rose was taken to many different therapist one including Doctor Walker who talked to her in third person even when

TITLE: Water Based Drilling Fluid Analysis EXECUTIVE SUMMARY: Analysis of drilling fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and

Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

Raising Awareness By: Tina Vu As a cadette‚ The Girl Scout Silver Award is one of the most important things to achieve in my life. This is an important step to help me build leadership and organization. My purpose for this project is to raise awareness for problems in the world‚ and maybe even discover solutions for them. Raising awareness isn’t just about educating people of what the things are‚ but on how you earn them as well as how you can stop yourself from getting such. What I basically

is to make more friends. In the article “The Quagmire of Social Media Friendship” by Curtis Silver‚ she believes that online friendship represents a merely “ghostly” version of actual friendship (1). These words of Silver describes that online friendship is dangerous because people can’t see whoever they are talking to‚ and they can’t believe if the person is trustworthy or not. I disagree with Silver on this argument because it plays an important role in life‚ which people use to share their

If you touch any of the metals‚ you MUST wash your hands at the end of the lab Procedure: 1. Collect the materials and put on safety equipment. 2. Observe the metals and record your observations. 3. Into separate test tubes‚ place each metal inside. Label accordingly to metal. 4. Measure 5mL of the copper (II)

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
