Determine the amount of heat (in kJ) given off when 1.89 104 g of ammonia are produced according to the following equation. Assume that the reaction takes place under standard-state conditions at 25.0°C.
Using the same sample of gas ( = 275 , = 43 ), we wish to change the pressure to 2750 with no accompanying change in volume or amount of gas.
Calculate the final temperature of 33 ml of ethanol initially at 20 degrees Celsius upon absorption of 541 J of heat. (density of ethanol =0.789 g/ml)?
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
Determine the pH of a 0.227 M C5H5N solution at 25°C. The Kb of C5H5N is 1.7 x 10-9.
Calculate Ka and Original Concentration of Weak Base, You have a solution of a weak base, the pH of which is 10.7532. If 10.000 mL of this solution will neutralize 6.655 mL of 0.07667
a sample of nitrogren gas is collected in a 100 mL container at a pressure of 688 mm Hg and a temperature of 565 degrees C. how many grams of nitrogen gas are present in gas sample?
The energy content of 1-liter of whole milk is 680 Cal. Using that data, determine how high can you climb (in meters) on a liter of whole milk.
