Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water: C6H5COOH + H2O ==== H+ and C6H5COO- The pKa of this reaction is 4.2. In a 0.53 M solution of benzoic acid, what percentage of the molecules are ionized?
effuse through a membrane. How long would it take the same number of moles of Ar(g) to effuse through the same membrane?

a sample of helium gas initially at 37 degrees celsius, 785 torr and 2.00L was heated to 58.0 degrees celcius while the volume expanded to 3.24L. What is the final pressure in atm.
if you were to draw all the products of radical bromination of ethane, how many structures would you draw
My lab is of an iodine clock reaction. I am being asked to calculate the initial rates for experiments 1, 2, and 3 from delta [S2082-]/ delta time. I know how to use the initial rate method however I am confused on how to obtain the initial concen..
Solid benzoic acid, C6H5COOH(s), is often used to determine the heat capacity of a bomb calorimeter, because the constant volume heat of combustion of this compound is known with high precision
What is the molar mass of the compound? Express your answer to two significant figures and include the appropriate units
How should the two heats of reactions for the neutralization of NaOH and the two acids compare? Why?
A mixture of carbon and sulfur has a mass of 9.0g . Complete combustion with excess O2 gives 23.0g of a mixture of CO2and SO2. Find the mass of sulfur in the original mixture.
Consider an insulated system containing 150 g of liquid water and 150 g of ice at equilibrium under atmospheric pressure. A total of 22 g of steam at 120±C is admitted to the system.
