I am trying to calculate geometry optimization of cyclodextrin, however, the computer always show error 2070 in gaussian. I used sem-empirical pm3 and try pm6, and tried to find any method to do this work, but every try could not work. I hope any body on Jiskha can give me ins...
the aprroximate method to solve the shrodringer equation for hydrogen like atom? Please help, thank
please help me to solve it, thank you so much in advance: propose organic compounds that are isolable with 1. Mn(CO)5(CpCo)(CpCo)C(Co(CO)4)3 2. Cr(CO)4(ì-PH)Cp*Mn(CO)
-3x + 2y = 8 x + 4y = -4 use substitution method to solve the linear system.
start from the Maxwell-Boltzmann distribution and derive an expression for the most probable speed of a gas of molecules at a temperature T. Go on t demonstrate the validity of the equipartition conclusion that the average translational kinetic energy of molecules free to move...
chemistry, Please help.
Please tell me where I can find the articles ( free) to represent the Setvens rearrangement and Favorskii rearrangement. I have to have them for presentation but I have not taughed about these reaarangenment yet. I hope somebody on Jiskha will help me to find it. I really appr...
Ionic bonds and covalent bonds, which one is the stronger. My present teacher said that covalent bond is the strongest one. I learned ionic interaction is the strongest and many chem. books say so. Now i am confused. Is my present teacher right. Please explain this for me, and...
mol Na2S = (0.01mol/L)*2.00ml*1L/1000mL = 0.002mol mol Hg(NO3)2 = 50.0ml*(0.0005mol/L)*1L/1000mL = 0.000025=2.5*10^-5 Hg(NO3)2 limiting reagent max mass of precipitate = 2.5*10^-5 * molar mass of Hg(NO3)2
why we have to normalize the proton NMR areas to determine the mole % oa a compound in a mixture?
4.6*10^-3 = [NO2]^2/[N2O4] => [NO2] =3.48*10^-1
