Aluminum dissolves in HCL according to the equation written below, whereas copper does not react with HCL: 2Al+6HCL ---> 2AlCl3 + 3H2 a 35 gram sample of copper-aluminum alloy is dropped into .750 L of 3M HCl, and the reaction above proceeds as far as possible. If the alloy contains 77.1% Al by mass, what volume of hydrogen gas would be produced at 22 degrees Celcius and 728 torr?
what is the concentration of H2 in the water in grams per milliliter? (See Appendix G in your textbook for the vapor pressure of water.)
What is the pH of a buffer that results when 0.50 mole of Na3PO4 is mixed with 0.75 mole of HCl and diluted with water to 1.00 L? The acid dissociation constants for phosphoric acid
How much energy (in kilojoules) is required to convert 225 mL of diethyl ether at its boiling point from liquid to vapor if its density is 0.7138 g/mL?
What amount of solid NaOH must be added to 1.0 L of a 0.13 M H2CO3 solution to produce a solution with [H+]= 3.4×10-11 M ? There is no significant volume change as the result of the addition of the solid.
What would you expect the measured decay rate to be 4.00 hours later? The half-life of Ru-97 is 2.79 days.
Which of the following wave functions are eigen functions of the operator d^2/dx^2? If they are eigen functions what is the eigen value
The m for this nuclide indicated an excited nuclear state that decays to the ground state by gamma emission.
mass m in a one dimensional box of length L? If the answer is yes, then express the energy of this trial wavefunction in terms of h, m, and L?
