Draw the structures of the E and Z stereoisomers of 1,4-diphenyl-2-butene-1,4-dione and label which is the cis and which is the trans
Why do aldehydes undergo nucleophilic addition faster than ketones? Explain based upon the transition state (applying Hammond's principle) and electronic and steric actors.
Given the following two solutions: 0.200 M HC2H3O2(aq) with pKa = 4.76 0.200M NaOH(aq) A mixture is made using 50.0 mL of the HC2H3O2 and 25.0 mL of the NaOH. What is its pH?
A 2.00 x 10^-3 mole sample of actylsalicylic acid was dissolved in 15.00 ml of water and titrated with .100 M NaOH. The equivalence point was reached after 20.0ml of NaOH solution had been added.
In a first order decomposition in which the rate constant is 0.0181 sec-1, how long will it take (in seconds) until 0.484 mol/L of the compound is left, if there was 0.548 mol/L at the start?
Consider a steel tank whose volume is 49.0 L and which contains O2 gas at a pressure of 18100 kPa at 29°C. What volume would the gas occupy at STP?
Litre of white gas, and density of the gas is 0.710 g/cm 3 . Calculate the mass of the fuel and express your answer in kgs?
Mercaptoacetic acid and NH3 were introduced, production of the complex with the former resulted in the release of an equivalent amount of EDTA, which required a 22.85-mL titration with 0.07238 M Mg2+. Calculate the percent Cu and Ni in the alloy.
