write the formula of the conjugate base for each of the following acids: a)HCO3^- b)CH3-NH3^+ c)HPO4^2- d)HNO2 e)HBrO
A syringe containing 1.64mL of oxygen gas is cooled from 95.9°C to 0.8°C. What is the final volume of oxygen gas?
A mixture of 40 Ml of methyl butyrate (MW-102.1 g/mol,d-0.89 g/mL) and 10 mL butyric acid (MW=88.1 g/mol, d=0.96 g/ML) is distilled.
A compound A (C22H27NO) is insoluble in acid and base but reacts with concentrated aqueous HCl and heat to give a clear aqueous solution from which, on cooling, benzoic acid precipitates.
Using the same assumptions and approximations you used in lab, determine the molar enthalpy change (in kJ/mol) for the reaction below, assuming that CH3CO2H dissociates completely in water.
How do the units mol/L and ppm compare? You will be given a 100.5 ppm iron stock solution (the iron is ferrous ammonium sulfate hexahydrate, (NH4)2Fe(SO4)2 x 6H2O. Report its molecualr weight in g/mol, and determine the concentration of the stock ..
