At a given temperature, 1.18 atm of F2 and 5.91 atm of Br2 are mixed and allowed to come to equilibrium. The equilibrium pressure of BrF is found to be 1.044 atm. Calculate Kp for the reaction at this temperature. F2(g) + Br2(g) <=> 2 BrF(g)
Assuming an ideal solution, what is the molecular mass of the compound?
Given the initial concentrations of 0.10 atm NO2 and 0.10 atm N2O4 in a 1.0 L flask, what will be the equilibrium partial pressure of NO2? N2O4(g) ? 2 NO2(g) Kp = 0.660 at 319 K
Explain why and calculate the difference between the delta S° values at 298 K for the complete dissociation of the two complex ions. (Hint: the value delta H is about the same for both systems.)
Determine how much Ammonia would be formed if 187 grams of calcium carbonate CaCO 3 are formed?
Glycerol, C3H8O3, is a water-soluble liquid of density 1.2656 g/ml at 15oC. Calculate the molarity of a solution of glycerol made by dissolving 40.000 ml glycerol at 15oC in enough water to make 250.000 ml of solution.
A solution is prepared by dissolving 3.65 g of an unknown nonelectrolyte in 15.00 g of cylcohexane (tf = 6.6 oC and kf = 20.0 oC/m).
The company is interested in the drug's value because only the dissociated form of the chemical is active in preventing cholesterol buildup in arteries.
Nitrogen and hydrogen gases react to form ammonia gas. N2(g) + 3 H2(g) 2 NH3(g) At a certain temperature and pressure 1.4 L of N2 reacts with 4.2 L of H2. If all the N2 and H2 are consumed, what volume of NH3, at the same temperature and pressure,..
