Calculate the pH of the final solution
A solution is made by dissolving 25.6 g of NaOH in approximately 450 mL of water in a volumetric flask. The solution becomes quite warm, but after it is allowed to return to room temperature, water is added to total 500 mL of solution.
Sulfur dioxide reacts with chlorine at 227 oC: SO2(g) +Cl2(g) ↔ SO2Cl2(g) Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of SO2 and Cl2 are placed in a 1.00 L reaction vessel.
How much heat is required to convert 27.0 grams of ethanol at 28 degrees celcius to the vapor phase at 78 degrees celcius?
Determine the amount of heat required to raise the temperature of a 153 g bar of gold by 50.0C. (specific heat of gold = 0.128 J/g.C)
The distribution coefficient, K= conc. in ligroin/conc. in water, between ligroin and water for solute A is 7.5. what weight of A would be removed from a solution of 10g of A in 100 mL of water.
Assemble the alcohols (have the formula of C4H10) in the order of increasing reactivity with concentrated HCl.
A 9.775 g. gaseous mixture contains ethane (C2H6) and propane (C3H8). Complete combustion to form carbon dioxide and water requires 1.120 mol of oxygen. Calculate the mass percent of ethane in the original mixture.
The solubility of a certain compound in ice-cold water is .19g in 100mL. its solubility in hot water is 3.35g in 100mL.
Determine the initial quality and temperature of the fluid mixture prior to heating. [quality x1 = 0.182, T1 = 113.3°C] b) Determine the final volume of the steam after heating. [0.546 m3 (546 liters)] Note: 1000 liters - 1 m3
