What is the molar concentration of Cl- in a solution prepared by mixing 25.0 mL of 0.025 M NaCl with 35.0 mL of 0.050 M BaCl2? What is pCl for the mixture
Explain why lattice energy calculations based on the born mayer equation reproduce the experimentally determined values to within 1 percent for LiCl but only 10 percent for AgCl given that both compounds have the rock salt structure
A chemist adds 120.0mL of a 1.12mol/L silver nitrate solution to a reaction flask. Calculate the mass in grams of silver nitrate the chemist added to the flask
Using the "unit conversion method", derive an equation to calculate the heat produced from the HCl-NaOH reaction, and write your equation on Sample Calculations A
Explain what is the molar solubility of AgCl in 1.0 M K2S2O3 if the complex ion Ag(S2O3)23- forms. The Ksp for AgCl is 1.8 *10(-10) and the Kf for Ag(S2O3)23- is 2.9*1013.

A solution of acetic acid, HC2H3O2, on a laboratory shelf was of undetermined concentration. If the pH of the solution was found to be 2.39, what was the original concentration of the acetic acid? ___M
Suppose that 0.3 g of AlOOH (FM 59.99) plus 150 mL of 3M KOH are diluted to 1L to give the same species produced by Al(OH)3. Write mass balance equations for aluminum and potassium.

Suppose you were tasked with producing some nitrogen monoxide (a.k.a. nitric oxide). I'm sure this is often requested of you. You can do it by combusting ammonia (be careful!). The equation would be as follows: 4NH3 + 5O 2→ 4NO + 6H2O. If you form ..
