Elena Chen CH 221-227 November 3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into

For this case study I will be using The Cycle of Change (TCC) or otherwise known as the Transtheoretical Model of Change (TTMC) by Prochaska & DiClemente (1983). This theory was originally used to facilitate and understanding process of behavioural change (Horwath & Morrison 2001). Originally used to understand the process of change for people that wanted to stop smoking‚ it is now applied and used with a wide range of issues. For example‚ treatment from a range of genetic concerns‚ domestic abuse

Revenue Cycle The revenue cycle is a set of four business activities: Sales order entry‚ shipping‚ billing and cash collections. To each of these activities there are related administrative organisational activities. It is all associated with providing the goods and services of a company to their customers and collecting the payments for these sales. Information about the revenue cycle activities also flows to the other accounting cycles which are: the expenditure cycle‚ the production cycle‚ the

Carbon Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release

The Main Parts of the Water Cycle The main parts of the water cycle are evaporation‚ condensation‚ and precipitation. They go together in a circle/cycle called the water cycle. None of these parts can be missing. (Well‚ everything in the water cycle is needed.) Evaporation- Evaporation is when water turns into water vapor and flows up into the sky. You can’t see it because it’s now gas and gas is invisible. Evaporation usually happens on hot‚ rainy days because the sun’s energy

My original purpose for beginning this education was to achieve a master’s degree. I had no thought process put into the idea except simply achieving the degree. As time progressed into my first semester my competitive nature kicked into gear. I did not just want to achieve a degree and slide by the next two years I wanted to excel. I had found my drive again and I wanted to soak up everything I possibly could about technology. A considerable amount of time and effort needed to be put forth

THE ROCK CYCLE ● ● ● ● There are three main types of rocks: igneous‚ sedimentary‚ and metamorphic. Each of these types of rocks are formed in different ways and each type of rock can be changed into the other types of rock. This process is called the Rock Cycle. The rock cycle is the process that makes and recycles rocks. IGNEOUS ROCKS ● ● ● ● ● ● Igneous rocks are formed from magma. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface‚ time and weather break the
