Cucl2 Research Paper

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 copper 2 oxide and water when heated. When solid CuO reacted with sulfuric acid, the copper returned to solution as an ion (Cu2+). The cycle of reactions was completed with the reaction where elemental copper was regenerated by Zn and Cu

Deborah Bell April 17, 2012 Chemistry 1212K Lab Synthesis Report Introduction In this Chemistry Lab the main objective is to perform accurate chemical analysis for the quantity of elements and compounds in a sample. There will be a compound made then synthesized. The methods used were acid-base titrations, redox

A new compound CU466 is a potential potent inhibitor of Dihydrofolate Reductase to treat methotrexate-resistant breast cancer

Designed by Lee Schmidt and Brian Curley, this 18-hole championship golf course proves the perfect course for any player. Maintained to the highest of standards, the wide fairways and wavy greens prove to be easily playable, and have become a trademark at Copper Canyon. If this doesn't encourage you to play here, perhaps you will be indulged by the surrounding landscapes that prove to make Copper Canyon a truly special course. You will also find that the surrounding landscapes is not all that this golf course offers in regards to its beauty, as over 11 beautiful lakes are featured on the course itself, making an all round mesmerizing golf course.

The reaction between Copper (II) Chloride and aluminum has a formula that follows this basic single replacement formula. Aluminum was able to replace copper during the reaction because it is higher on the activity series. If aluminum

Purpose: In this experiment, the experimenter will determine the chemical formula for the copper chloride hydrates using the law of definite proportions. The hydrated compound has a general formula of CuxCly•zH2O, with the variables x, y, and z. The variables represent the whole number ratio of moles that will be the “true” chemical formula of the hydrate. The chemical formula shows the number of atoms of each element in a compound.

Copper Sun, by Sharon Draper, an emotionally driven story. the story tells the journey of Amari, a young African girl who is kidnapped from her home and sold into slavery. Amari faces a wide range of emotions throughout her journey. The most powerful emotions Amari faced were sadness and fear. The reason Amari was sad because as she was being kidnapped, her family has been murdered because the people who kidnapped her thought that her parents were too old to be sold into slavery. She had fear because also because her family was murdered, and she didn’t know what was going to happen to her when she got to the boat and to be sold into slavery. Also she didn’t know what her future was going to be like.

XIII. Carefully remove the copper metal from the filter paper onto the watch glass. (with a spatula) Place a 400 ml beaker on a hot plate contained with water. Carefully place the watch glass before the water boils to dry the copper metal. (Use the tongs to handle the hot watch glass)

-Pledged to manufacture without causing environmental damage. 4. Are atoms made of molecules or a molecule made of atoms? -Molecules are made of atoms. 5. How does the arrangement of particles in a gas differ from the arrangements in liquids and solids?

In conclusion, changing lifestyle can reduce consTipton rate because every activity in lifestyle help to improve constipation. The important solutions are dietary fiber intake, adequate fluid per day, and exercise. If patients concentrate to lifestyles, patients will reduce constipation by themselves.

In ancient China, copper coin has been a major currency for over three thousand years, and the mining of copper can be traced back to 11 century BC in the Western Zhou Dynasty. In the southeast of Huangshi city, Hubei province, Tonglvshan mining site was found in 1973 having over

The reaction characteristics of basic copper carbonate 〖mCuCO〗_3⋅n〖Cu(OH)〗_2 were observed by changing the reaction mole ratio. The reaction mole ratio of sodium carbonate to copper chloride (II) was controlled from 1.08 to 1.68. Fig. 1 shows the XRD patterns of copper carbonate powder. At a reaction ratio of 1.08, paratacamite

5000 years. Copper was probably used around 8000 B.C by people living along the Tigris and Euphrates rivers. In 6000 B.C, Egyptians learned how to hammer copper into things they wanted. Around 3500 B.C, People first learned how to melt copper with tin to make bronze. So the period between 3000 B.C Lamps are also attached to these helmets in case some of the lighting in the mine goes out leaving a miner

Copper For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have
