Q: A sample of copper was heated to 120.00 °C and then thrust into 200.0 g of water at 25.00 °C. The temperature of the mixture became 26.50 °C.a. The copper sample lost how many joules?1.26 x 103 J 78.2 J 1.26 J 22.2 J 20.9 Jb. What was the mass in grams of the copper sample?34.7 g 21.7 g 34.3 g 2170 g 27.1 g: Copper Sample

Q: i had the copper iud placed about 5 months ago ever since i have had HORRIBLE cramps, EXCESSIVE bleeding to the point that i dont think i can lose anymore blood and i get it 2 times a month and both times are for 8-10 days and when i have sex i get a painful sharp piercing pain are these normal side effects.: NO i would get it checked out . It should not hurt you during sex , just your partner will feel the string in the beginning a little till it softens over time. Periods are stronger though and last about 6-7 days with me. But i get them only once a month and every three months a light 2 day spotting as the cycle changes. But other than that i have no problems with it. I have it now for 2 years. So go see a doctor and make sure its still in the right place.

Q: I want to bulk-anneal copper using a kiln. What temp should I program the kiln to?: anneal okorder

Q: should i invest in copper bars or silver? why? and why is scrap copper cheap but bars expensive? if i sell the bar will it sell for scrap price or bar price?: Copper isn't assayed. Scrap copper is cheap because it is just that, scrap. It would include copper wire (covered in PVC). Also lots of different types of copper alloy.Like Beryllium Copper which gives off Arsenic when melted. You probably wouldn't invest in physical copper because you would need so much of the stuff. I am guessing but a tonne of copper is about $1400 isn't it?

Q: I need to write a paragraph on copper, what are some good things to write? Dont just give me the link to wikipedia, that doesnt help me. The first person to like actually answer my question will get 10 pionts, so why not just try?: Name: copper Symbol: Cu Atomic number: 29 Atomic weight: 63.546 (3) r CAS Registry ID: 7440-50-8 Group number: 11 Group name: Coinage metal Period number: 4 Block: d-block Description Here is a brief description of copper. Standard state: solid at 298 K Colour: copper, metallic Classification: Metallic Availability: copper is available in many forms including bars, foil, sheet, granules, plates, powder, shot, turnings, wire, insulated wire, mesh, evaporation slugs, and rods.

Q: Can someone explain the source of the blue color of the solution after the reaction between copper and silver ion?: What happend is termed a displacement reaction the position the iron reacts with copper and displaces it. Iron sulphate is formed , copper sulphate turns into copper and plated the nail the change in colour of the answer's because of the formation of FeSO4 extremely of CuSO4. CuSO4 + Fe -----> FeSO4 + Cu

Q: Getting rings and they're made of copper alloy. Will it rust?: No okorder

Q: I need to know, if copper nitrate (produced by the reaction of nitric acid and copper) a solution or a precipitate??my notes say it is a blue-green precipitate.my teacher says it is a blue ppt.my textbook says it is a blue green solution??any help?!: Most of the nitrate salts are soluble in aqueous solution .Hence Copper sulphate in aqueous solution is a blue green solution.In aqueous solution Cu2+ ion is hydrated and colour is due the d-d transition.

Q: What instruments do you have in a brass tube?: Tuba (Tuba)The tuba is the largest bass brass instrument in the orchestra. It has a deep, deep and dignified tone, and is the basis of orchestra and Sonata, as well as double bass. The structure is composed of three parts: mouth, pipe body and machinery. There are four to six pistons (Rotary is more common). A hug Tuba tuba, ring type large and large transit (commonly known as "Su Safeng") three, after only two for the band or orchestra.There are many large shapes, in addition to holding type, ring type, Su Safeng mentioned earlier, there is an excellent California (Tenor tuba). The orchestra also uses G, F, and C for tuba. Large in a band, mainly bass, harmonic, or rhythmic, rarely used in solos. In fact, it not only large bass, treble is also very beautiful, so modern composers occasionally Tuba playing the melody, such as Ravel's orchestration of "pictures at an exhibition" in the "ox" theme, is playing with a large.
