A mixture of 8.0mol of H2 (g) and 4.0mol of O2 (g) is placed in a sealed evacuated container made of a perfect insulating material at 28 degrees C. The mixture is ignited with a spark and it reacts to form liquid water. Find the temperature of the water.
containing too little oxygen to allow complete combustion of the fuel is called a rich mixture. A high-performance heater that burns propane, C3H8(g), is adjusted so that 100.0 g of O2(g) enters the system for every 100.0 g of propane. Is this mix..
The value of Ka in water at 25 degrees Celcius for benzoic acid, C6H5COOH (aq), is 6.3 x10-5 M. Calculate the pH and the concentration of the other species in a 0.0200-M aqueous solution of C6H5COOH (aq).
As you saw in Part B, the vapor above the cyclohexane-acetone solution is composed of both cyclohexane vapor and acetone vapor.
The [Br] of the resulting solution if 0.672 M. Assuming the volume is additive, calculate the molarity of the first solution?
The Ka of butyric acid, C3H7COOH is 1.5 x 10-5. What is [C3H7COO-] in a 0.397 M solution of C3H7COOH
