As you saw in Part B, the vapor above the cyclohexane-acetone solution is composed of both cyclohexane vapor and acetone vapor. What mole fraction of the vapor above the solution, Xcy(vapor), is cyclohexane?
What molar ratio of benzoate ion to benzoic acid would be required to prepare a buffer with a pH of 5.20? [Ka(C6H5COOH) = 6.5 × 10-5]
When a 1.30-g sample of ethanol (alcohol) is burned in a calorimeter, the heat released increases the temperature of 870g of water in the calorimeter from 18.5 C to 28.9 C .
The flask was then shaken until the solution was uniform. A 45.0- sample of this glucose solution was diluted to 0.500 . How many grams of glucose are in 100. of the final solution?
prepared by dissolving 33.2 g of the compound in sufficient water to form 250 mL of solution. The solution has an osmotic pressure of 1.2 atm at 25 °C. What is the molar mass (g/mole) of the compound?
How many moles of sulfur dioxide, SO2 are contained in a 5.0 L container at STP?
A 62g piece of ice at 0 degrees C is added to a sample of water at 6 degrees C. All of the ice melts and the temp of water decreases to 0 degrees C. How many grams of water were in the sample?
What are the most important energy considerations which determine whether or not this compound can be prepared?
The design calls for reheating the liquid after the temperature has dropped to seventy degree Celsius the determine about how many stags and how many heaters are required for this process?
In the combustion of propane for energy, how many kilojoules of heat are produced when 2 kilograms of propane are completely combusted in the presence of excess oxygen
Draw the major product for each of the following reactions. Make sure that you draw a major product that could be isolated, not just an intermediate or something that would be present only in low equilibrium population.
Experimental solid-oxide fuel cells that use butane (C4H10) as the fuel have been reported recently. These cells contain composite metal/metal oxide electrodes and a solid metal oxide electrolyte. Consider the following unbalanced half-reactions:
A volume of 120 mL of H2O is initially at room temperature (22.0 C). A chilled steel rod at 2.00 C is placed in the water. If the final temperature of the system is 21.1 C , what is the mass of the steel bar?
