A 158.5mg sample of pure copper is dissolved in a small amount of nitric acid, giving copper(II) ions in solution. This solution is then diluted to a final volume of 1.00L. What is the molar concentration of copper(II) ions in the final solution?
What are the differences between sub-energy levels and orbitals? (My professor said they were different.)
If oxygen gas is collected over water at 60 degree C and 1.10 atm, what is the partial pressure of the O2?

How many moles of Cr(OH)3 will dissolve in 1.00 L of a solution with a pH of 5.13. (Assume the pH does not change as the Cr(OH)3 is placed in the water.) (Ksp for Cr(OH)3 is 6.7 x 10-31)
Are the following statements about a 1.0 M solution of a strong acid, HA, true or false? [A-] › [H+]: True/False
Sodium bicarbonate is called baking soda because when heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread. Calculate the volume (in liters) of carbon dioxide by heating 4.37 g of sodium bica..
A gas cylinder that contains argon has an internal volume of 6.88 L. A pressure gauge attached to the cylinder reads 1870 psi (1 atm = 14.7psi) at 20.0C.
The activation energy for a particular reaction is Ea = 14.20 kJ. What percentage of the molecules are at or above the activation energy at 500.0 K
