solution and our final step was getting rid of the liquid waste and observing the copper powder at the bottom of our beakers. We noticed that although we performed many different chemical reactions on the copper‚ it never changed elements. The copper cycle supports the claim that copper is an element. Although it the copper changed color and state‚ it never disappeared or went away‚ it was there the entire time. If you mix nickel and hydrochloric acid‚ it produces water‚ nickel

mechanism in which a trapping center‚ or an associated catalyst‚ (S) successively accumulates four charges. The S4+state produces O2and returns to the ground state S‚‚. 5. Besides So also the first oxidized state S+ is stable in the dark‚ the two higher states‚ Sp+ and S3+are not. 6. The relaxation times of some of the photooxidation steps were estimated. : : The fastest reaction‚ presumably S + S‚‚ has a (first) half time < 200 psec. The S state and probably also the SJ state are processed somewhat

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

The flora population changed by increasing. Because the plants grow in the soil‚ the increase of carbon in soil leads to an increase in carbon in the plants. 2. A) The carbon level in the soil has increased in 2070. The carbon level increases as does the plants therefore an increase in the amount of plants. B) The decomposer rate will increase because there are more plants due to the increase in carbon and soil‚ therefore the death of the plants will be decomposed. The deforestation rate increased
