    Please help with this chemistry II question.?

    Since: A = Ao*e^(-kAt) B = Bo*e^(-kBt) A=4.19B becomes: Ao*e^(-kAt) = 4.19 * Bo*e^(-kBt) since Ao=Bo, we can cancel them out: e^(-kAt) = 4.19 e^(-kBt) ln[e^(-kAt)]=ln[4.19e^(-kBt)] -kAt=ln4.19-kBt plug in the k's and use your calculator to find t

    What are some good books in French for an intermediate learner?

    Good for vocabulary-building but also not too boring to read.

    a chemistry question for you to help me with?

    First find how much energy is required: q = (62.0C-25.0C)(.997g/mL)(265mL)(4.184J/g*K) q = 40900 J Then find how much energy is in one mole of photons: E = Nhc/w where N is Avogadro's number, h is Planck's constant, c is speed of light, and w is wavelength E= (6.022*10^23 1/mole)(6.63*10^-34...

    What are some good/famous fiction from other cultures?

    Classical or contemporary fiction that have been translated to English. Not necessarily ones that are well-known in the US. I am especially interested in looking into French and Middle-Eastern literature.
