Communication
Copper wire has long been the preferred conductor material in the majority of cables used for power and telecommunications. Having high conductivity combined with a ductility that makes it easy to draw down to close-tolerance diameters, it can also be
readily soldered to make economic, durable connections. It is compatible with all modern insulation materials but its good oxidation resistance means that it can also be used without any surface protection.
Plumbing & Heating
Copper tube is the standard plumbing material for potable water and heating systems in most European countries, and the preferred material of the professional plumber.
Roofing
Copper sheet is light in weight, easy to work and join, visually attractive and extremely durable. It resists attacks by air and moisture.
The metal's long-established use for roofing and cladding buildings is accentuated in the modern architect's renewed interest in copper for its natural properties and, perhaps especially, for its excellent resistance to atmospheric corrosion. The ever-changing patina is an integral feature of the appearance of a building as it weathers, the original copper glow gradually changing to a succession of warm brown tones before reaching the final distinctive green.

Theoretical yield
1 mole ----→ Cu Co3 + Cu O + Cu
mass of 1 moles 124g 80g 64g
mass expected 2.5 1.2g
Actual yield 0.1g
Theoretical yield: 0.g/1.2 x 100= 8.3%
Materials and procedure
Severity 5 = Fatal 4 = Major injury 3 = Minor injury 2 = Negligible 1 = None
Likelihood 5 = Certainty 4= Probable 3 = Possible 2 = Remote 1 = Unlikely
Rate = Severity x Likelihood
15 -> 25 Too dangerous, consider not doing activity;
12 -> 14 Activity possibly dangerous, but might be carried out with considerable care and control;
8 -> 11 Activity fairly safe but should be carried out with care and appropriate controls;
1 -> 7 Activity safe but should be carried out with care and appropriate controls;
Evaluation
The experiment went wrong because we separated it the wrong way. The way we can change and make it better we can get a more precise heating then use them as much more. Also the experiment went wrong because the calculations fo the temperature didn’t turn as planned.
We could have tried to improve it by making the temperature and using a more careful way to separate the metals.
We used the equipment in the wrong way we should have been more careful and try to do the experiment the right way in order to get better results.
Balance equation
Copper carbonate ➔ carbon oxide ➔ carbon dioxide Thermal decomposition
Cu Co3 CuO Co2
In this reaction we used a lot of heat to make the chemical react
Copper oxide + carbon ➔ carbon dioxide + copper Displacement decomposition
2CuO C Co2 2Cu
We used a lot of heat. The carbon burn and as it was burning it turned into fire.
