a) Assuming ideal behavior, what is the solubility of AgCl(s) in 1.00 x 10-4 M NaCl if only Ksp is considered? (b) What is the solubility AgCl(s) if all 4 equilibria are considered for the 1.00 x 10-4 M NaCl? AgCl(s) ? AgCl(aq) So = 3.0 x 10-7 AgCl(s) ? Ag+(aq) + Cl-(aq) Ksp = 1.78 x 10-10 AgCl(aq) + Cl-(aq) ? AgCl2- (aq) K2 = 66.7 AgCl2-(aq) + Cl-(aq) ? AgCl32- K3 = 1.0

Combustion of 3.00 g of this compound produced 7.06 g of CO2 and 1.93 g of H2O. What is the empirical formula of the unknown compound?
A major component of gasoline is octane (C8H18) . When octane is burned in air, it chemically reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O).
Consider a system with four energy levels: 0E, 1E, 2E, 3E, where E is kT (E can be represented by epsilon and T is 100K). Assume that there are 10 particles. Provide an expression for energy, heat capacity and entropy. Plot all as a function of T
