Explain why the main reaction between acetophenone andp-anisaldehyde is the mixed aldol reaction rather thanself-condensation of acetophenone or the Cannizzaro reaction of p-anisaldehyde.
How many grams of calcium phosphate are theoretically produced if we start with 3.40 moles of Ca(NO3)2 and 2.40 moles of Li3PO4
a molar heat capacity at constant volume of 3/2R initially at 298K and 10l is expanded with the surroundings maintained at 298K to a final volume of 20L in three ways ways a) isothermally and reversibly b) isothermally against a constant extenal p..
Kc = 9.7 at 900 K for the reaction NH3(g) + H2S(g) --> NH4HS(s) If the initial concentrations of NH3(g) and H2S(g) are 2.0 M, what is the equilibrium concentration of H2S(g)?
Calculate the entropy change of the surroundings associated with this heat transfer. Assume the weight of an average adult is 80.0 kg.
What is the silver ion concentration in a solution prepared by mixing 357 mL of 0.392 M silver nitrate with 469 mL of 0.504 M sodium phosphate?
