  1. The solution contains the same kinds of ions but not the concentrations may not be equal. Neutralization?
  2. Sulphur dioxide is on the cover of the longan, what will be formed if we put it in running water? Are sulphuric acid and sulphurous acid both formed? If yes, by how many steps? Thanks for your concerning on me
  3. Without water, we can't do anything. This is a deadly problem for some country with only a little bit of water. Considering some special properties of water, scientists make theory that a planet without water would have a very small chance of having organism. Why is water so special and can we find out its mysteries? (A strange shape, high specific heat capacity, solid state is less dense than liquid state..) According to a calculation, the probability of god is over 50%. Do you believe the god?
  4. hehe sorry YT 2SO2 + 2H2O + O2 ----> 2H2SO4 is instead of the two equation, ok? Actually, in the newspaper, the writer did not mention whether it's sulphuric acid or sulphurous acid, I just guess it ! Anyway, when we wash some longan with running water, sulphurous or sulphuric acid is formed?
  5. I have watched it before. Has it been produced long time ago and how long? In HK, it seems to be produced about one-two year and so far
  6. One day, I heard some sulphur dioxide on some fruit from newspaper. It said that sulphur dioxide react with water to form sulphuric acid. Is SO2 + H2O ----> H2SO4 SO2 + H2O ----> H2SO4 + O2 true? However, they seem that they doesn't make sense. They can't be balanced. Therefore, I guess 2SO2 + 2H2O + O2 ----> 2H2SO4 right?
  7. Do atoms or molecules of different compound have different speed (kinetic energy) when the temperature is the same? If they have the same mass?
  8. hahah A virus?? it is called lsass.exe I scan it with antivirus software, but it didn't show me that's true. Last, I go internet and type lsass.exe in google web site. Over one million of web site gives the information-----it's virus However, I don't think so
  9. How to remove that bad worm
  10. I think one electron bring more electricity than two electrons
  11. Why do scientist always encourage us to have sushi within a short period of time? Doesn't bacteria grow in our body?
  12. Why does silicon dioxide is not a molecule but a lattice crystal? The electronegativity ?
  13. YT and budull, do you use msn?
  14. It is found that the gravity force is about 9.8m/s2 It is usually omit the air resistance when we calculate the air resistance. One day, I asked myself how long does it take from jumping from the top of the building to the ground. And I did a bad calculation, only some seconds. I believed that it's wrong and I go to ask for information here
  15. Is electricity formed when one or more electrons of an atom is/are moved?
  16. Thanks everyone. I am used to using norton anti-virus and Iparmor
  17. ?What do you mean ?
  18. Which is more dangerous-alternating current or direct current? Is direct current only found in battery circuit but not the circuit which electricity come from power station?
  19. thanks How about a program called "spooler.exe" Is it necessary for Window startup?
  20. I never thought you but just remind bigyin. I know you are good.
