Consider the base monosodium phosphate and Write the structure of the conjugate acid of this base and explain why an aqueous solution of NaH2PO4 would be ineffective for extracting C7H6O2 from a diethyl ether solution. Given that the pKa of this conjugate acid is 2.1?
Calculate the number of moles of electrons needed to produce 5.12g of copper from the electrolysis of a solution of CuSO4.
When 0.0500 mol of HCl is reacted with 0.0500 mol of NaOH in 50.0 mL of water, the temperature of the water increases by 13.7°C. Calculate the heat of the reaction for the following thermochemical equation
Calculate Kp for the reaction 2NOCl(g) ->2NO(g) + Cl2(g) at 400degrees C if Kc at 400 degrees C for this reaction is 2.1 × 10-2
We are investigating the keto-enol tautomerization of acetylacetone (pentane-2,4-dione) in an aqueous solutions at 25 degrees Celsius. The standard reaction Gibbs energy for the enol ketone tautomerization is -3.64 kJ/mol.
What is maximum light wavelength (nm) to be absorbed for creating electron-hole pairs in semiconducting material cadmium telluride (CdTe)? CdTe has a band gap of 1.44 eV.
suppose a can contains gas at a pressure of 755 mm Hg and a temperature of 25 degrees celsius, what would be the pressure if the can was heated to 1155 degrees celsius ?
A semipermeable membrane separates two solutions. On one side of the membrane the concentration of sodium ions is 0.87 mol/L, and on the other side the concentration of sodium ions is 2.5 mol/L.
When 0.097 moles of Magnesium hydroxide (Mg(OH)2) is dissolved in water, how many moles of ions are released into the solution ?
describe one or more simple chemical tests that would distinuish acetaminophen from ibuprofem
Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H, in enough water to make 5.00 102 mL of solution and then titrate the solution with 0.163 M NaOH.
A researcher attempts a substitution reaction with two different reagents, water or hydroxide ion, to see which route is better. Draw the major,
600.0 mL of 0.240 M perchloric acid, HClO4(aq) was added to a high quality constant-pressure calorimeter containing 400.0 mL of 0.300 M KOH(aq). Both solutions have a density of 1.000 g mL-1 and a specific heat of 4.184 J g-1°C-1.
