What is the pH of a solution made by mixing 100.00 mL of 0.20 M HCl with 50.00 mL of 0.10 M HCl? Assume that the volumes are additive.
container it was heated to 800K, and at equilibrium the pressure of CO ws found to be .497 atm. Calculate the equilibrium constant Kp for the reaction.
Charcoal found under a stone at Stonehenge, England, has a carbon-14 activity that is 0.50 that of new wood. How old is the charcoal? (The half life of carbon-14 is 5,730 years.)
A gas is confined to a container with a massless piston at the top.A massless wire is attached to the piston. When an external pressure of 2.00 rm atm is applied to the wire, the gas compresses from 5.90 to 2.95 L. When the external pressure is in..
They hydrogen atom is not actually electronegative enough to form bonds to xenon. Were the xenon-hydrogen bond to exist, what would be the structure of XeH4

calculate the external pressure that must be applied to seawater, 1.14 M total ion concentration at 10 degrees celcius if the maximum concentration allowed in the product water is 166 mg/L
Answer the questions below with the data provided: 15 mL of 5% NaOH (w/v) is used to deprotonate the unknown carboxylic acid. The TBME is washed with an additional 10 mL of the NaOH solution and then 20 mL of water which are all combined.
Osmosis occurs when the solvent molecules move from a solution of higher solute concentration to a solution of lower solute concentration.
