- Q: What are the chances of a copper IUD affecting someone who has a fatty liver? The patient is not an alcoholic, just slightly obese. Noticed weight gain since IUD was placed almost a year ago. Could there be a link between the copper and the build up of fat in the liver as in Wilson's disease?
- Hepatitis B is the main easy severe liver an infection in the worldwide. that's understood to be the main effective reason for liver cancer. The illness is led to by making use of the hepatitis B virus (HBV) that assaults the liver. The virus is transmitted by using blood and actual fluids that contain blood. this could happen by using direct blood-to-blood touch, unprotected intercourse, and illicit drug use. it could additionally be handed from an contaminated lady to her new-born in the process the delivery technique. scientific comments regardless of the undeniable fact that asserts that approximately 50% of people who carry the virus by no skill improve any indicators. Hepatitis B virus may well be avoided by making use of using a secure and helpful vaccine.
- Q: A 150g piece of copper heated to 80°C is placed in the water. The water is stirred thorougly. After sufficient time elapses, to what temperature does the water change?Assume that no heat is transferred to or from the environment. The specific heat of water is 4.2 J/g.K , and copper's is 0.40 J/g.K
- ? Q1 = [m○(copper).cp(copper) + m(water).cp(water)]T1 Q2 = m(copper).cp(copper) T2 ? ??? Q1+Q2 = Q3 = [(m○(copper)+m(copper)).cp(copper) + m(water).cp(water)].T3 ; T3 > T1 → T3 = {[m○(copper).cp(copper) + m(water).cp(water)]T1 + m(copper).cp(copper).T2]/ [(m○(copper)+m(copper)).cp(copper) + m(water).cp(water)] → T3 =((0,1*400 + 0,2*4200)*20 + 0,15*400*80)/(0,25*400 + 0,2*4200) = 23,83 °C @+ ;)
- Q: I came across some [maybe] copper printings of 1880s San Francisco. I'm wondering who made them, how, why, and what they might be worth.Help?
- Copper printings? Do you mean a copper etching? Is the image etched into the copper? Look for a signature or initials. That will determine who made them and if they're worth anything.
- Q: Who knows GREE air conditioning, two pieces of smallpox confidential, match what big copper tube?
- 9.52 /15.88 has many models, or it may be 6.35/12.7. answered
- Q: We did this experiment in my chemistry class the other day.we had:Solid copper(II)sulfate pentahydrate + fire. What is the product??CuSO4·5H2O(s) + O2(g) --> ????P.S. please balance the equation
- How much heat? Simple oven heat will take the pentahydrate water away and turn the copper (II) sulfate from blue to white. The presence of the ligand water bonds have the electrons in the d-orbitals releasing energy seen as blue in the EM spectrum. Without the water the copper (II) sulfate is white. If you added enough heat I imagine you converted the copper sulfate into a copper oxide. At 650 °C, copper(II) sulfate decomposes into copper(II) oxide (CuO) and sulfur trioxide (SO3)
- Q: In an experiment, a student isolated 6.356 g of pure copper from an initial sample of 9.902 g of copper chloride. Determine the empirical formula of this copper chloride compound. Show your work.
- Copper chloride here can be copper (II) chloride (CuCl2) or copper (I) chloride (CuCl). The balanced chemical equation for the decomposition of the copper chlorides: CuCl2 = Cu + Cl2 2CuCl = 2Cu + Cl2 Determine the number of moles of 6.356 g pure Cu. Note: 1 mole Cu = 63.5463 grams Cu 6.356 grams Cu x (1 mole Cu/63.5463 grams Cu) = 0.1000 mole Cu Determine the moles CuCl2 and CuCl that will produce this mole Cu. CuCl2: 1 mole CuCl2 produces 1 mole Cu 0.1000 mole Cu x (1 mole CuCl2/1 mole Cu) = 0.1000 mole CuCl2 CuCl: 2 moles CuCl produce 2 moles Cu 0.1000 mole Cu x (2 mole CuCl/1 mole Cu) = 0.1000 mole CuCl Convert these moles CuCl2 and CuCl to grams. Note: 1 mole CuCl2 = 134.4527 grams CuCl2 0.1000 mole CuCl2 x (134.4527 grams CuCl2/1 mole CuCl2) = 13.44527 grams CuCl2 Note: 1 mole CuCl = 98.9995 grams CuCl 0.1000 mole CuCl x (98.9995 grams CuCl/1 mole CuCl) = 9.89995 grams CuCl --> nearer to the amount of initial reagent Therefore, the empirical formula of the compound is CuCl or copper (I) chloride. That's it!n_n
- Q: acids seem to clean copper more than dissolve it. i wanted to make copper sulfate crystals and some other pretty colored copper crystals, but acids seem to clean the copper more than combine with it. i know copper is low on the reactivity list, but it does become oxidized. can i turn it into any form of copper salt easily and then change that salt into the desired crystal?
- Dissolve Copper
- Q: Alrighty then. so, I have cooper pipe with brass screens. And I prefer to smoke a certain powder through it. Unfortunately, I often get a mouth full of the powder, which of course completely defeats the purpose Can someone please help and tell me what i am doing wrong? lt;Many many thanks- The Novice
- Let me guess you're white aren't you?
