Q:Plot Temp vs Time of Copper?
from what I read you can expect the copper to gain 1.6 kJ/s so E = 1.6 t probably OK to take To as 20 C - room temp then E = m c delta(T) delta(T) = E/ (m c ) look up c - specific heat of solid copper - get it in kJ / (kg*C) so temp as a function of time as the copper warms to its melting point T = To + delta(T) = To + E/(m c) = To + 1.6 t / (m c) use this to generate temps from time 0 up to the melting T then you will have a flat portion as the copper melts without energy change use E = m Lf to get total needed to melt it and E = 1.6 t to get the time for the graph finally look up c for liquid copper and use T = To + 1.6 t / (m c) with To as the MP of copper maybe run the time beyond melting for about the same amount of time it took to warm the solid copper to MP - this would give some symmetry to your graph you would wind up with a graph having two upward sloping segments joined by the horizontal melting event

Q:How to make copper(II) Sulphate?
Not really. If you must know, your question is rambling and a bit hard to follow. Do you want to know why you need to react CuO with H2SO4 to make CuSO4(aq) and not simply react copper metal with H2SO4 to make copper sulfate? We'll put the answer in the form of a couple of chemical equations... CuO(s) + H2SO4(aq) --> CuSO4(aq) + H2O(l) Cu(s) + H2SO4(aq) --> no reaction That should sum it up. Copper metal does not react with sulfuric acid. Copper(II) oxide is what we call a basic anhydride. The word anhydride literally means without water. If you take a water molecule away from Cu(OH)2, an Arrhenius base, you get CuO. Take away water.... Cu(OH)2 = Cu-OH-OH (copper and two hydroxides) --> CuO--HOH (see the water?) --> CuO + H2O (evaporate the water to leave the basic anhydride) Basic anhydrides react with acids, just as bases do. CuO + H2SO4 --> CuSO4(aq) + H2O(l) As for copper metal and acids.... Metals above hydrogen in the activity series easily react with acids to produce the metal ion and hydrogen gas. Copper is below hydrogen in the actiivity series and does not react with the H+ in acids. It therefore, won't react with H2SO4. Copper does react with HNO3, though. But not for the reason you might think. Copper is oxidized by the nitrate ion, NO3-, to Cu2+, while NO3- is reduced to NO gas. When copper reacts with nitric acid we see a reddish brown gas, which is NO2, coming off. The reaction produces NO, which combines with oxygen, O2, to make NO2 gas. From this information you should be able to formulate answers to your questions. .

Q:Some questions about copper?
The Wikipedia article on copper will answer these questions.
Q:Why does Copper have more free electrons compared to Zinc if...?
well the fact is the electronic configuration of copper would have been (4s-2),(3d-9)...but what happens is one electron from 4s orbital jumps into the 3d orbital giving more stability and a sate of lesser energy..and the new electronic configuration becomes 4s-1,3d-10..... where as Zn has both 4s and 3d orbitals filled and thus cannot loose it because they provide stability!...now in case of copper if the only electron from 4s is lost then it has 3d orbital filled which is again a stable state! thus that electron is available as free electron..... only thing is that if copper looses that electron then it becomes more stable.. while in zinc the 4s orbital is filled and thus provides extra stability..in short the electron cannot be made freely available for stability reasons......thus copper has more free electron than zinc!
Q:Which is better, PPR plastic pipe or copper pipe?
copper pipeThe utility model has the advantages of corrosion resistance, bacteria elimination, etc., and is the superior product in the water pipe. The interface of the copper pipe is provided with two kinds of clamping sleeve and welding. There are problems of aging and water leakage in the sleeve for a long time, so most of the users who install the copper pipe adopt welding type, and the welding is that the interface is welded together by oxygen, so that the water pipe can not leak as the PP-R pipe. One of the defects of copper pipes is that heat conduction is fast, so the hot water pipes outside famous copper tube manufacturers are covered with plastic and foaming agent to prevent heat distribution. Another disadvantage of copper pipes is that they are expensive, and few of the water supply systems are made of copper tubes. If you want to change the pipe and feel the copper pipe is good, it is recommended to use the welded interface. PPR tubeAs a new type of water pipe material, it can be used as cold pipe or hot water pipe. Because of its non-toxic, light weight, high pressure resistance and corrosion resistance, it is becoming a kind of popularized material. It is also suitable for hot water pipes and even pure drinking water pipelines. By using the technology of melting PPR pipe interface between the tubes completely fused together, so once installed by the pressure test, not as long as there are aluminum pipe and PPR pipe Water Leakage aging phenomenon, will not scale. The main defects of PPR pipe are: high temperature resistance, pressure resistance slightly less working temperature for a long time can not exceed 70 DEG C; the length of each section is limited, and can not bend pipe laying construction, if the long distance or the corner, would be used in the construction of large joints; pipe fittings are cheap but the price is relatively high.There are pros and cons, the family recommended the construction of PPR difficult, low prices
Q:Copper has density of 8.94 g/cm^3 and crystallizes with the face-centered cubic unit cell.?
Hi simone! I am answering you from Italy. The question is really difficult to solve. My suggestion is as follows: Atomic weight of Copper = 63.55 g/mol Copper density = 8.97 g/cm^3 You can easily see that 8.97 grams of copper has a volume of 1 cm^3. You have to calculate the number of Cu mole which occupies 1 cm^3. That means: 8.97 g copper /63.55 g/mol = 0.1411487 mol in 1 cm^3 which means that 0.1411487 mol *6.022* 10^23 molecules/mol = 8.49997*10^+22 molecules of Copper in 1 cm^3. From these data you can calculate the volume per molecule =1 cm^3/8.49997*10^+22 molecules= =1.17647*10^-23 cm3/molecule You have to consider the molecule shape as a sphere. The volume of a sphere is given by: V= 4/3 pi*r^3 --> where pi = 3.14 so, 1.17647*10^-23 = 4/3 pi * r^3 --> r = 1.41091*10^-8 m = 141.091*10^-10 --> m = 141.091 Angstroms. Angstrom to picometer (A to pm) --> pm = 100 *A 141.091*100 Amstrongs = 1410.91 pm --> 'pm' is the abbreviation of picometer. Result: r = 1410.91 pm NOTE: 6.022* 10^23 molecules/mol is the value of the Avogadro constant [NA] which is defined as the ratio of the number of constituent particles [N] (atoms or molecules) in a sample to the amount of substance n (mole) through the relationship NA = N/n [Source: Wikipedia] Kind regards from Italy.

Q:The 3P air tube is generally what specifications please enlighten!
Fixed frequency 3P machines with an on-line pipe diameter of 15.88 and 6.35, and now air-conditioning manufacturers to reduce costs, it may be metric 15 and 6; inverter air conditioners are generally 12.7 and 6.35, metric 12 and 6.
Q:Woodwind and brass instruments, how to distinguish?
Upstairs, you say no, woodwind and brass instruments orchestra is in accordance with the actual sound division for voice, string instruments, woodwind, brass, and percussion instruments of color. Woodwind instruments commonly used include the flute,Piccolo, Oboe, clarinet, bass, clarinet, soprano saxophone, alto saxophone, bassoon, contrabassoon. The flute, piccolo Sax are made of metal materials. But the brass instrument is basically a gold color. It's better to tell the difference.
