Baryon (4/13)



  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. I think one electron bring more electricity than two electrons
  10. Why do scientist always encourage us to have sushi within a short period of time? Doesn't bacteria grow in our body?
  11. Why does silicon dioxide is not a molecule but a lattice crystal? The electronegativity ?
