The concentration of SO4 is .5 M in a certain solution of Al2(SO4)3. what is the molar concentration of Al in the solution?
Why do solutions of iodide ion in water appear yellow when I- is oxidized to I2 by a suitable oxidizing agent, while solutions of I- in CCl4 or CHCl2 appear violet when the same oxidationis done?
The temperature rises from 19.25C to 22.17C. If the heat capacityof the calorimeter is 98.6J/C, calculate the enthalpy change forthe above reaction on a molar basis
The principle quantum number defines the shell (which is roughly, but not quite exactly, the row, or period, of the periodic table). Demonstrate the difference between the rows of the periodic table
How many milliliters of a stock solution of 11.0 NHO3 would you have to use to prepare 0.320 of 0.350 NHO3
To determine its identity, 0.150g of the unknown was dissolved using 10.00ml, 0.531 M HCl. Three drops of methyl orange was added to the solution and then titrated with 0.2440 M NaOH.
Electronic spectroscopy makes transitions between electronic states, as well as vibrational (and rotational) states. Explain why no general vibrational-state selection rule exists for electronic transitions.
