  1. But don't they need more kinetic energy for photosynthsis when increased in light intensity, such as conducting water and some other movement, then they need more oxygen for the respiration part, right?
  2. Increase in light intensity speed up the rate of photosynthesis. Does increase in light intensity also speed up the rate of respiration? I think so, but my teacher never talked about it.
  3. Would Anyone kindly tell me? I need this answer .please
  4. does the look on electronegativity is a correct way?
  5. Does molecule share ? Oh may be I know, in ionic bond the ions share with ions totally , but molecule keep together close only by electrostatic forces and don't react(combine).Am I right?
  6. I have two questions, could anyone give hand? 1.Why does some chemical emit smell, like sodium hydroxide? 2.Does carbon dioxide fly into atmosphere layers( its density is higher than air )? I know it does absorb heat, so this question is such for further fun
  7. I think hydrogen atom being cation in some polyatomic ion like ammonium. I think it doesn't go ionic way during normal conditions.
  8. Where can find some Cute animal icons?
  9. 1.Why the chemical formula of an ionic compound shows [the types of ions present and the ratio of one type ion to other ]differently from the chemical formula of covalent compound ( molecule )shows [acutal number of atoms of element]?? 2.Why aren't ionic compound not molecules? Seek for your helps
  10. What are the effects of absorbing too much phenylalanine ?
  11. How to prove 1/f= 1/u +1/v?
  12. Thanks buddy
  13. Ozone is formed by lightning, why don't we pass electricity into the atmosphere (O2) and get some ozone for preventing too much ultraviolet radiation?
  14. I think he wants to ask how to predict the product which will be formed. Actually, I want to ask
  15. Can anyone suggest me some free web site contain php script?
  16. I think there may be a difficult experiment that I don't know, I want to ask it. We know if the angle of incidence is greater than 0 degree , we can actual see the light beams reflected in the same degree. However, if the angle of incidence is 0 degree, they said it will reflect at 0 degree also. I'd like to know what experiment did they carry out?
  17. Which scientist do you know the most, and why?
  18. I know how to install a phpbb forum in local computer. However, I don't know how to create a phpbb forum in other web providing server such as yahoo, would anyone teach me, please?
  19. How can scientist know that when a line pass along the normal, from less denser to denser , it still reflects along the normal ?
  20. Is "all ionic bonds are partially polar covalent" only for hydrogen bonds?
  21. Do these kinds of knowledge are taught in physical chemistry>?
