Calculate the work done if a gas is compressed from 8.1 L to 3.9 L at constant temperature by a constant pressure of 2.3 atm, and give your answer in units of joules.
what volume will it occupy? Assume constant pressure. Note the temperatures are given in two different units. Be sure to change each to deg K first.
Important information about pH and Molarity, You add 5 drops of .100 M HCl to 100ml of "pure" water. Assuming that the volume of one drop is .035ml, calculate the expected pH of the resulting solution
After the reaction comes to equilibrium, an additional 1.00g of O2(g) is added to the system. What is the expected partial pressure of SO2(g) then?
What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)? but I cant get this one right can someome please help.
Each reaction needs to be balanced and all physical states (s, l, g, aq) noted (you may need to look these up or read the lab to determine the physical states).
if the molarity of the HCl solution was actually greater then the lable indicated would it affect the calculated value for the number of moles of HCl that reacted.
calculate the concentration (molarity) of AgCl in a saturated solution.
Erythro-2,3-dibromo-3-phenylpropanoic acid undergoes eliminiation by an E1 pathway in water solvent (Part A conditions),
Write the oxidation reaction for L-Ribose and α-D-Lyxose (use the Benedict' reagent as an oxidizing agent). Write the reduction rection (hydrogenation) for D-Idose and β-D-Psicoe.
A solution is prepared by condensing 5.01L of a gas, measured at 27.0 degrees celcius and 769 mmHg pressure, into 72.1g of benzene. Calculate the freezing point of this solution.
How many moles of chlorine molecules correspond to 7.40 x 1026 molecules of Cl2?
