Problem- The solubility of CuCO3 is measured and found to be 1.88E-3 g/L. Use this information to calculate a Ksp value for copper(II) carbonate.Ksp=?
I want you to clarify the chemistry in this above problem.
A solution is made by mixing 12.0g of NaOH and 70.0mL of 0.200m HNO3. Calculate the concentration of OH- ion remaining in the solution.
What wavelength, of light would be necessary to ionize an electron at the n = 3 state in a He+ cation
A copper wire (density = 8.96 g/cm3) has a diameter of 0.44 mm. If a sample of this copper wire has a mass of 50. g, how long is the wire?
Hardness in groundwater is due to the presence of metal ions, primarily Mg2 and Ca2 . Hardness is generally reported as ppm CaCO3 or mmol/L Ca2 . To measure water hardness, a sample of groundwater is titrated with EDTA,
Write an equation to show how the base NaOH(s) behaves in water. Include states of matter in your answer.

Calculate the pH of a solution prepared by mixing 20.5mL of a 0.500M sodium fluoride solution with 32.5mL of a 0.750M hydrofluoric acid solution.
Which choice is closest to the longest wavelength that will remove an electron from the n=3 level of the hydrogen atom? (hint: what would you use for the value of nfinal when the electron is completely removed from the atom?)
You dissolve 12.6352 g of potassium iodide in water and bring the volume of solution to 250.0 ml. What is the molar concentration of KI and what volume of 0.0436 molar hydrochloric acid is required to react with 30.0 ml of 0.0278 molar LiOH?
Calculate the number of moles of the H2O2 in the 10.00 mL sample in every titration from the volume of KMnO4 used and the stoichiometry of the reaction.
