for another. Just this semester‚ I has math class with an Asian girl‚ I noticed at the end of the day‚ I also saw her in my chemistry class. Towards the middle of the semester‚ I realized I would need help in math as well as her notes from chemistry on the days I won’t be attending. I decided to go up to her after pre-calculus one day to ask if she’s in my 3:40pm Chemistry class‚ to my surprise‚ she told me she wasn’t. I asked her if she was sure because the other Asian looks just like her! She said

When a really large unstable isotope changes into to smaller isotopes that are 2 completely different elements. the nucleus has to be larger than 230(mass). They are really slow and spontaneous. Fission = splitting. Can create a chain reaction. (picture above). Critical mass= must be enough mass in a reaction or enough fission type mass‚ fissionable mass‚ for the reaction to continue to go on.(minimum amount). Sub critical mass= mass of fission material that doesn’t have enough to keep the reaction

INTRODUCTION: The purpose of this experiment is to measure the formation constant of the tetraamminecopper(II) ion by colorimetry. Anhydrous copper sulfate (CuSO4) is white‚ which means that it does not absorb light in the visible region of the spectrum. The hydrated copper sulfate (CuSO4 - 5H2O) is blue. The structure of the compound can be represented more accurately as Cu(H2O)4 SO4 - H2O where four water molecules are bound to the copper ion and the fifth is a water of crystallization. The

Article Excerpt Access to the world’s oil supplies is a principal factor behind US government policy‚ as the events of the past two years have unmistakably shown. And no wonder: possessing only 2% of the world’s reserves of oil‚ the US consumes 25% of global oil production at a cost of $150bn per year. Of this‚ 70% is in the form of gasoline (petroleum) or diesel fuel for transport use. Given the finite supply of oil‚ this cannot go on. Certainly‚ by 2050‚ competition for oil supplies will be
