Assume Bromine trifluoride can be ready by the direct combination of the elements:
Br2 (g) + 3F2 (g) ? 2BrF3 (g)
Explain what volumes of Br2 and of F2 measured at the same temperature also pressure are needed to prepare 50.0mL of BrF3?
After adding the two portions into the calorimeter setup and following the procedure outlined in the experiment, you determine the temperature of the mixed portions of water to be 45*C. what is the heat capacity of the calorimeter?
Hydrochloric acid B) Ammonium Hydroxide 2) Identify the geometry of the iron(III) complex in water and the complex ions produced in the above reactions

indicate the direction of the bond polarity of NH3 and CH4. are either of the molecules polar. is ClH3 polar. why or why not.
Calculate the change in entropy of the copper, taking C(p,m) = 24.4 J/K /mol. The experiment is then repeated with the copper immersed in a stream of water that maintains its temperature at 293 K. Calculate the change in entropy of the copper and ..
Drag the flask and drop it on the lower half of the burette to connect them. Open the Data window and click on the flask. Click the Pushpin icon in the blue bar of the Data window to lock its display to the flask's contents.
a gas mixture contains helium and oxygen at partial pressures of 255 torr and 0.450 atm. what is the total pressure in
A piece of silver (25 g) is heated to 100 degrees celsius, then dropped into 42.5 g of water with a temperature of 21.7 celsius. Assume they come to the same temp, what is the final temp of the silver and water? (Molar capacities: Ag 25.351 J/mol*..
13.00 moles of gas are in a 5.00 L tank at 22.6 C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a = 2.300 L^2*atm/mol2 and b = 0.0430 L/mol.
