While a 1.00 L flask containing 1.500 atm of gas A is joined with a 1.00 L flask containing 0.750 atm of gas B, as well as the stopcock between the flasks is opened, also the gases are allowed to mix thoroughly, the following reaction proceeds at constant temperature. Explain what is the resulting total pressure of gases in now-joined flasks after the reaction proceeds to completion?
2A(g) + 3B(g) A2B3(g)
A. 0.375 atmB. 0.750 atmC. 0.625 atmD. 0.225 atm
Suppose you are given 150 mg of an unknown mixture that contains three compounds, and you are told to separate the compounds using column chromatography, using alumina as a stationary phase. How would you decide what solvent or solvent system to u..
