    Plasma is the combination of positive ions and free electrons. These electrons are no longer associated with the particular atom because of very high temperature.
  2. Sodium chloride and lead nitrate would react forming lead chloride and sodium nitrate. Lead nitrate would form precipitate and sodium nitrate will be in the filterate. They can be separated by filtration. Now where is sodium chloride?
  3. Compete combustion of Heptane would yield CO2but incomplete would yield CO.So Heptane and oxygen would give carbon monoxide and water in combustion reaction.
  4. We cannot measure the internal energy in a system, we can only determine the change in internal energy.
  5. Scientists developed a revolutionary antifreeze solution called FreezePruf.Check out the link for more information. http://www.florida-palm-trees.com/quick-way-protect-palm-trees-cold/
  6. Visit: http://alison.com/..Here you can learn lot more about programming and computer skills..
  7. Yes I agree that we are not benefited by these arguments.But the effects are getting worse.Not only humans but the aquatic life and wild animals are being punished.We have to think about it.
  8. very helpful sites..I must say "excellent"
  9. Alchemist by Paulo Coelho is the book I really like.
  10. If looking at the body weight:brain weight ratio, the hippopotamus is not looking too smart while talking about the intelligence of mammals.
  11. With today’s levels of atmospheric carbon dioxide so high, the ocean’s help comes at a cost to marine life and the millions of people who depend on healthy oceans. http://www.livescience.com/38219-oceans-acidifying-with-rising-co2.html
  12. Yes..Keep your spirits high
  13. I suggest you to take chemistry as a major.I have good experience in this subject as a major. while talking about the difficulty level every body has different approach.In my opinion general chemistry is easiest.I find difficult then inorganic because of too much reaction mechanisms.Physical chemistry seems very interesting to me.Analytical Chemistry is also not much difficult one can learn it by little effort.I find Bio Chemistry very tough because learning different structural formulas of similar compounds is inconvenient for me.
  14. I would suggest following books of Chemistry for high school.In my opinion these are really helpful. 1. Chemistry : The central science By Theodore L. Brown http://www.amazon.com/Chemistry-Central-Theodore-E-Brown/dp/0321696727/ref=sr_1_1?s=books&ie=UTF8&qid=1375511164&sr=1-1&keywords=CHEMISTRY+THE+CENTRAL+SCIENCE+Theodore+L.+Brown+H.+Eugene+LeMay%2C+Jr.+Bruce+E.+Bursten+Catherine+J.+Murphy 2. Chemistry By Steven and Susan Zumdahl http://www.amazon.com/Chemistry-Steven-S-Zumdahl/dp/1133611095/ref=sr_1_fkmr0_1?s=books&ie=UTF8&qid=1375511416&sr=1-1-fkmr0&keywords=Chemistry+By+Steven+and+Susan+Zumdahl+newre+edition 3. Chemistry for everyone By Suzanne Lahl http://www.amazon.com/Chemistry-Everyone-Helpful-Primer-College/dp/0615386601/ref=sr_1_1?s=books&ie=UTF8&qid=1375512190&sr=1-1&keywords=Chemistry+for+everyone+By+Suzanne+Lahl I would alo suggest you a very helpful website related to the problems in Chemistry http://www.chemistryhomeworkhelp.biz/
  15. "Chemistry: The central Science" is a very good book related to chemistry. http://www.amazon.com/dp/0321696727#reader_B0054S6MF0 "Zoology by Miller/Harley" is also a very good book. http://www.amazon.com/dp/0073228079
  16. I think you are talking about Molecular graphics..If so Check out the links below for complete information regarding to the drawing of molecular structures through different computer programmes and soft wares. http://en.wikipedia.org/wiki/Molecular_graphics http://en.wikipedia.org/wiki/List_of_molecular_graphics_systems
  17. I know about one very good book related to high school and college level chemistry which is "Chemistry: the central Science".It contains good information about electronic structure and bonding, Organization of matter, states of matter, nomenclature, Stoichiometry and Thermochemistry etc. http://www.amazon.com/Chemistry-Central-Theodore-E-Brown/dp/0321696727/ref=sr_1_1?s=books&ie=UTF8&qid=1375376882&sr=1-1 I also want to let you know about one very nice and solution oriented website related to all fields of chemistry and can provide you help related to the problems in chemistry. http://www.chemistryhomeworkhelp.biz/ I hope it will help you.
  18. So,Should I assume that the electricity generated is the result of energy produced when spontaneous reaction between water and Co2 takes place?If so why are they associating it with the ions?
  19. I want to listen.Can you give me the link? Because this is not working here.
  20. The point related to science is that they forced co2 into water and other liquids, where the carbon dioxide split into positive and negative ions.These ions were used up in the generation of flow of electrons by further processing. you can see the whole mechanism in this link: http://www.huffingtonpost.com/2013/07/27/carbon-dioxide-power-plants_n_3660989.html I liked the post that's why wanted to share it here.Thanks for telling me the rule.Next time I will post accordingly.
