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

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

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

where does the water cycle gets its energy from? the water cycle gets the energy from the sun. why do we need the water cycle? since 97% of the earth is covered by salt water we can not drink it. we can remove salt from water but it could be very expensive. how does water get into oceans? when clouds can’t hold any more water it comes as precipitation and lands in the ocean. what is the water cycle made up of? it is made up of six different traits. condensation‚infiltration‚runoff‚ evaporation‚ precipitation

Oxygen cycle From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search The oxygen cycle. The Oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within its three main reservoirs: the atmosphere (air)‚ the total content of biological matter within the biosphere (the global sum of all ecosystems)‚ and the lithosphere (Earth ’s crust). Failures in the oxygen cycle within the hydrosphere (the combined mass of water found on‚ under‚ and over the surface of a planet)

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
