1) Write the equilibrium constant expression for the reaction : 3A + B <-> 2C 2) Calculate Kc for the above reaction if [A] = 6.1 x 10^(-3) M; [B] = 3.9 x 10^(-1) M; and [C] = 5.0 x 10^(-5) M at equilibrium.
What is the molar solubility of Mns, in grams per liter, in a buffer solution that is 0.110 M HC2H3O2 -0.505 M NaC2H3O2? For Mns
A solution is prepared by dissolving 0.60g of nicotine in water to make 12mL of solution. The osmotic pressure of the solution is 7.55atm at 25 degrees C
A saturated solution of copper(II) sulfide, CuS, has [Cu^2+]=1.1x10^-18 M. what is the value of Ksp for CuS
Concentrated stock HCl has a molecular weight of 36.46 and contains 32g of salt for every 100g of acid (termed as 32% w/w). To prepare molar solutions %w/w must be converted into %w/v by considering the density of stock HCl which is 1.16.
A syringe filled with air can be used to test the relationship between the temperature and the volume of a sample of gas. The syringe has a movable plunger that allows an enclosed sample of gas to be held at a constant external pressure, so the ga..
