Calculate the difference between the molar enthalpy and the molar internal energy of carbon dioxide regarded as an ideal gas at 298.15K and 754 mmHg
What products would you expect from the reaction of 1 mol of 1,3-butadiene and each of the following reagents? (If no reaction would occur, indicate that as well.)
The concentration of KBr in a solution prepared by dissolving 2.13 g of KBr in 897 g of water is moral
When the liberated hydrogen gas is collected over water at 29 degrees celsius and 752 torr, the volume is found to be 343 mL. The vapor pressure of water at 29 degrees celsius is 30.0 torr. What is the mass percentage of aluminum in this alloy?
calculate the pH of the buffer after the addition of 0.15 mL of 6M HCl based on the known value of Ka for acetic acid
Plutonium-240 (PU-240) is a byproduct of the nuclear reaction that takes place in a reactor. It takes one thousand years for 10% of a 4.60 g sample to decay. (Nuclear decays are first-order reactions)
How many moles of HNO3 are present in 33.5 mL of a 2.20 M solution of nitric acid?
Copper dissolves in nitric acid, producing copper (ll) nitrate. After reaction with sodium hydroxide and heating, copper nitrate changes to copper (ll) oxide. Calculate the percent yield of this process if 1.075 g of copper produced 1.075 g of cop..
It was found that 19.31 mL of an HCl solution are needed to react completely with 322 mL of a LiOH solution that has a pH of 11.56. What is the molarity of the HCl solution?
Consider the figure that shows the distillation apparatus. Describe the practical reasons behind the direction of the flow of water through the condense. It will not let me upload the picture of the figure. It keeps saying that there is an error? ..
Using a stock solution of 95.4ppm MgCO3, you are directed by your instructor to make calibration standards of 1.0, 7.5, and12.0 ppm. If you use 100mL volumetric flasks to make the solutions, what volume of stock solution will you require for each ..
Why would it have been expected for iodine to have emission lines that included all colors of the visible spectrum? explain
