Compute the equilibrium constant (Keq) for the reaction of equimolar amounts of acetophenone as well as sodium hydroxide to generate the enolate. The pKa values of acetophenone as well as water and 19.0 and 15.7 respectively. This is all the information if more is desired, however you can use theoretical values if you want or need to for that matter.
Liquid mixtures of sodium and potassium are used in some nuclear reactors as coolants that can survive the intense radiation inside reactor cores. Calculate the energy required as heat to melt 250 kg of sodium metal at 371 K.
The density of air under ordinary conditions at 25 C is 1.19g/L. How many kilograms of air are in a room that measures 11.0ft x 11.0ft and has an 10.0ft ceiling. 1 in = 2.54 cm (exactly); 1L= 10^3 cm^3.
Assume that all ethanol is transformed into CO2 and assume the lake contains 10^8 liters of water. Explain your answer with the chemical reaction involved and any assumptions you make.
At equilibrium the vessel contains 0.40 mol of PCl3 (g) as well as Cl2(g) and undissociated PCL5(g). What is the equilibrium constant for the decomposition of PCl5 to PCl3 and Cl2 at this temperature.
You use 32.0 mL of NaOH to titrate 100. mL of HCl and 22.2 mL of NaOH to titrate 50.0 mL of 0.0836 M H2SO4. Find the unknown concentrations. NaOH HCl
When determining the effective nuclear charge for a 1s electron, Slater's rules dictate that the other 1s electron must have a value of 0.30 not 0.35. Why?
