MHS Chemistry The Copper Cycle In this experiment you will start with a piece of copper metal, dissolve it in concentrated nitric acid, precipitate it as copper II hydroxide, dissolve it in hydrochloric acid, and reduce everything back to copper metal. You will observe the appearance of each reactant and product. Finally, you will carefully calculate the percent of copper recovered, keeping in mind what we have learned about significant digits.
Given the almost frenetic enthusiasm in global metals markets, super-cycle is synonymous for long-term bull market. It may well be true that copper is in a super-cycle, but, in contrast to the optimists who expect steadily rising prices as far as Copper cycle eye can see, hard facts would suggest we are close to the end of an extended period of rising prices that actually began during the s.
Peter GoodburnManaging Director of WaveTrack Internationalprovides us with a chart of copper prices beginning from the early s with projections through Such a long-term perspective helps us gauge where we are today, how we got here, and the probability of a major new price surge versus the even greater likelihood of a sustained deflationary trend taking prices back to levels.
The chart alone without any further analysis provides several cautionary notes. Current prices remain below their peaks.
Past price mini-cycles i. Since the initial peak inprices have moved sideways with significant volatility. WaveTrack uses the more specific techniques derived from the Elliott Wave Principle to identify where prices are today in the context of the super-cycle and what to expect over the next several years.
The archetypal pattern for prices in the upswing can be monitored in a five-wave sequence— three waves of sharply rising prices waves 1, 3 and 5 punctuated by two intervening waves 2 and 4 of price retrenchment. In other words, in contrast to the bull market optimism, the dynamics of the super-cycle driving prices higher have already subsided.
Once a trend develops and completes a structural five-wave pattern in this way, a regression period that acts as the counter-balancing phase must follow. This takes the form of three main price-swings annotated A, B and C that, upon completion, partially retrace the preceding trend.
Quite often, this type of regression pattern forces an initial decline rapidly lower as wave A, but then prices turn around as wave B, resulting in an attempt to even higher levels than those marking the official orthodox conclusion of the super-cycle.
Therefore, a further retrenchment sometime later is likely as wave C.
Both the optimism that remains the dominant force in the market and inflationary expectations fueled by easy monetary policy are likely to send prices to substantially new highs for wave B i.Chemical Reactions of Copper and Percent Yield KEY Pre-lab (Review Questions) 1.

Beryllium copper (2 percent Be) is an unusual copper alloy in that it can be hardened by heat treatment. Copper is a part of many coinage metals. Long after the Bronze Age passed into the Iron Age, copper remained the metal second in use and importance to iron.
Defiance County, Ohio. Defiance County has a long history of change and growth. It is currently composed of twelve townships, Adams, Defiance, Delaware, Farmer, Hicksville, Highland, Mark, Milford, Noble, Richland, Tiffin and Washington covering square miles.
Copper Cycle Extension. You will now begin the process of getting the copper back into solution. In your first step you will begin with YOUR MASS of copper. _____grams Cu. Earth's anthrobiogeochemical copper cycle, mids. The thickness of arrows represents a rough approximation of magnitude to aid visualization.
The box arrow symbol indicates those reservoirs that are not in a state of mass balance, and are either accumulating or losing copper.
