Will Co(OH)3 precipitate from a solution that is initially 0.10 M in Co3+ and 1.0 M in SCN1- if the solution is buffered at pH 9.00? SHOW your work. {For Co(OH)3, Ksp = 1.6 x 10-44; for [Co(SCN)4] 2- , Kf = 1 x 103 }
Draw the Newman projection formulas for CH3CHBrCH2CH3 and sketch the potential energy versus rotation diagram for a 360o rotation of 2-bromobutane along C2 and C3 carbon atoms.
Suppose 1-chlorobutane were halogenated with bromine atoms instead of chlorine atoms. What effect would that have on the relative yields of the four bromochlorobutanes compared to the dichlorobutanes you determined
1.3 Kg of Ethane gas (C2H6 ) was heated from 27.0 degree Celsius to 78.0 degree Celsius. Calculate delta E at constant pressure. ( Cp= 52.92 j / K mol)
Calculate the density of hydrogen bromide gas (in g/L) at 733 mm Hg and 47 degrees Celsius
collected over water at 22 degrees C and the total pressure of the wet gas were 710 mm Hg, what would be the partial pressure of the oxygen?
State mechanism of aniline to acetanilide using ethanoic acid and ethanoic anhydride, then write mechanism of acetanilide top-bromoacetanilide using bromine, then state mechanism of p-bromoacetanilide to 4-bromoaniline using NaOH & HCl.
Calculate the mg/l of carbon dioxide required to react with 35 mg/l of calcium hydroxide and the m/l of precipitate formed.
an average man requires about 2.00mg of vitamin b2 per day. how many pounds of cheese would a man have to eat per day
At 850 c caco3 undergoes substantial decomposition to yield cao and co2. assuming that the delta hf values of the reactant and products are the same at 850 c as they are at 25 c calculate the enthalpy change (in kJ) i 198.7 g of co2 are produc..
What product was formed and why did this route to the ether fail. Suggest a different substitution reaction that should yield the desired product.
Problem- a) Decide which is more stable: an aryldiazonium cation, or a cyclohexyldiazonium cation? Use resonance structures to justify your answer. b) Upon heating to temperatures above 50oC, aryldiazonium salts decompose and evolve nitrogen gas.
Question- Write line-angle formulas for four deriviatives of carboxylic acids and arrange them in order of reactivity most reactive first and label each derivative.
