Many household cleaning products contain oxalic acid, H2C2O4, a diprotic acid with the following dissociation constants: ka1= 5.9*10^-2, ka2=6.4*106-5Calculate the equilibrium concentration of H3O^+ in a 0.20 M solution of oxalic acid.
Suppose one wated to take another approach where C is heated until 5% of the atoms occupy the electronically excited state. Consedering only the lowest-energy ground state and the elctronically excited state
How can diacetylmorphine be ionised in the blood and what will the effects of this be on the molecule in circulation? (I assume that it will be more soluble?)
An acre of corn can produce about 375 gallons of ethanol, using only the kernel of the corn for conversion to ethanol. Assume the energy input to produce an acre of corn is 15000000 kJ.
write the chem equation for the reaction which occurs when solutions of potassium sulfide and iron (II) chloride are mixed.
Calculate the vapor pressure of a solution prepared by dissolving 70.0 g of naphthalene, C10H8 (a nonvolatile nonelectrolyte), in 220.0 g of benzene, C6H6, at 20°C. Assume the solution is ideal. The vapor pressure of pure benzene is 74.6 torr at 2..
What is the pH of a propanoic acid - propanoate buffer that is 0.25M in CH3CH2COONa and 0.15M with respect to CH3CH2COOH.
Classify the substances according to the strongest solute-solvent interaction that will occur between the given substances and water during dissolution.
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
The indicator dilution method is a technique used to determine flow rates of fluids in channels for which devices like rotameters and orifice meters cannot be used.
Calculate the van der waals correction terms to pressure and volume for Cl2 at STP. The values of the van der waals constants a and b are 6.49L^2-atm/mol^2 and 0.0562 L/mol,
if a sample of gas at 25.2 C has a volume of 536 mL at 637 torr, what will its volume be if the pressure is increased to 712 torr.
Compute the molality of a solution containing 327 g glucose(C6H12O6) dissolved in 1.52 L of water. (Assume a density of 1.00 g/mL for water.)
