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
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...
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.
