Question- From its electronic configuration, predict which of the first 10 elements would be most similar in chemical behavior to the as yet undiscovered element 165.
It is not a question in the book, so I just need the full solution of deriving!
A pipette is used to add 32 mL of 0.2 M Pb(NO3)2 to a 261.0 mL solution of 0.3 M NaF. Determine the equilibrium concentration of Pb2+(aq) in the final solution. Ksp(PbF2)=3.6E-8.
What is the theoretical yield for this reaction under the given conditions? What is the percent yield for this reaction under the given conditions?
In a separate experiment, it was found that, for fixed temperature and pressure, a 0.100 L sample of this compound takes 1.97 times longer to effuse than does a 0.100 L sample of Ar(g). What is the molecular formula of the compound? draw possible ..

calculate the percentage of empty space in 1 mol of water at 25C. Obtain the density from the experiment " Some Measurements of Mass and Volume." The volume of a molecule of water can be taken as the sum of the volumes of the two hydrogen atoms.
A mixture of NO, CO2, and O2 gases has a total pressure of 2.5000 x 10^3 torr. If the partial pressure of NO is 800.0 torr and CO2 is 600.0 torr, what is the partial pressure of O2
A reaction has a standard free-energy change of -14.40 kJ mol-1 (-3.442 kcal mol-1). Calculate the equilibrium constant for the reaction at 25 °C.
A buffer solution is prepared by mixing enough acetic acid and potassium acetate to give 500ml of a solution that is 0.500 M acetic acid and 0.500 M potassium acetate. What is the pH of this buffer
a piston-cylinder device initially contains 0.5m3 of nitrogen gas at 400 kpa and 27 degc. an electric heater within the
Plutonium-239 is a byproduct of the fission reaction used to produce energy in nuclear power reactors. It has a half-life of 24,400 years. A student determines that it will take 97,600 years for the radioactivity of a Pu-239 sample to drop to one-..
Calculate the concentrations of Fe3+ and SCN- in the reaction mixture in part I when you add 10.00 mL of 0.200 M Fe3+ to 1.00 mL of 2.0 x 10-3 M SCN- and make up the total volume to 50.00 mL? What is the concentration of FeSCN2+?
