The alcohol content of hard liquor is normally given in terms of the "proof," which is defined as twice the percentage by volume of ethanol (C2H5OH) present. Calculate the number of grams of alcohol present in 1.00 L of 81-proof gin. The density of ethanol is 0.798 g/mL.
the standard electrode potentials calculate the standard free energy (kJ) for the given reaction.
Consider the following reaction: HC2H3O2 (aq) + H2O (l) = H3O+ (aq) + C2H3O2- (aq) Kc=1.8*10^-5 If a solution initially contains 0.260M HC2H3O2, what is the equilibrium concentration of H3O+ at 25C

The original sample is not pure, but is contaminated with a thermally stable compound. Will the reported mole ratio of CaO to CO2 be too high, too low, or unaffected? Explain
At room temperature benzoic acid dissolves in the less polar solvent, ether, but not very much in the more polar solvent, water. However, the deprotonated species, the benzoate ion, dissolves in water but not ether. What does this tell you about t..
