it's in Q#1 (as attached) I don't know how to explain why l amd ml (but not n) can cause energy degeneracy in one electron atom? (is it possible to explain the above in 3-4 lines? not just 1 line) (the deadline for this assignment has changed to Friday instead of Wednesday)
it's Q# 2 (as attached) I had done question# 2 (as attached) but I don't understand why I cannot arrive at the answer given by the question? I don't know did i make a mistake somewhere or should I do more?
I am given three unnormalized wavefunctions for the system:
psi(x) = 100e^x for x<-4
psi(x) = 0.73 cos[(pi)x/40] for-4
If one gram of Carbon 14 nuclides from an old bone is found to give off 0.478 decays (energy units) per minute, how old is this sample if originally the carbon-14 sample gives off 7.65 decays per minute, and the half life is 5715 years?
Ex. Heating zinc sulfide in the presence of oxygen yields the following: ZnS + O2 (arrow) ZnO + SO2 If 1.72 mol of ZnS is heated in the presence of 3.04 mol of O2, which reactant will be used up? Balance the equation first.
hydrogen bromide can be produced by a reaction among bromine, sulfer dioxide, and water as follows... S02 + Br2 +H2O (arrow) 2HBr + H2SO4 If 250 grams of SO2 and 650 grams of Br2 react in the presence of excess water, what mass of HBr will be formed?
Carbon Disulfide, CS2, is an important industrial substance. Its fumes can burn explosively in air to form sulfer dioxide and carbon dioxide. CF2(g) + O2(g) (arrow) SO2(g) + CO2(g) If 1.60 mol of CS2 burns with 5.60 mol of O2, how many mols of the excess reactant will still be present when the reaction is over.? Also . ...continues
Nickel replaces silver from silver nitrate in solution according to the following equation
7. Nickel replaces silver from silver nitrate in solution according to the following equation: 2AgNO3 + Ni (arrow) 2Ag +Ni(NO3)2 a. If you have 22.9 g of Ni and 112 f of AgNO3, which reactant is in excess? b. What mass of nickel(II) nitrate would be produced given the quantities above? 15. Sulfu ...continues
