When Cl2 is used as water disinfectant, the following reactions should be used to determine the concentration of different species.
Cl2(g) ------> Cl2 (aq) Kh = 8.0x10^-3 M
Cl2(aq) + H2o (l) -----> H+ (aq) + Cl(aq) + HOCl (aq) Kc= 4.5x10-4 M^2
HOCl (aq) ----> H+(aq) + OCl- (aq) Ka = 3.0x10^-8 M
Calculate the concentration of each species when pure water is treated with 100 ppm Cl2.
A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 180g of solution. The reaction caused the temperature of the solution to rise from 21.0 to 24.7degrees Celsius
Calculate the change in entropy (in J/K) for the following reaction at 298 K: C(s) + H2O(g) ? CO(g) + H2(g) Use entropy for graphite (diamond is too expensive).
If 10500 L H2 gas is reacted with an excess of N2 gas at 200 atm. and 500 C, how many moles of ammonia gas would be produced, assuming a 15% yield?

Insulin is a protein that is used by the body to regulate both carbohydrate and fat metabolism. A bottle contains 375 of insulin at a concentration of 50.0 . What is the total mass of insulin in the bottle?
burning 480 cm3 of propane measured at r.t.p,caused the temperture of 250 cm3 of water to increase by 42.5 celsius. calculate the heat of combustion of propane.
do not specify stereochemistry. (The absolute stereochemical configurations of chiral substances cannot be determined from the data.)
A calorimeter contains 17.0 mL of water at 15.0 degrees celcius When 1.40 g of (a substance with a molar mass of 69.0 g/mol) is added, it dissolves via the reaction X(s)+H2O(l)->X(aq)
