A gas occupying a volume of 263 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume?
The perovskite structure is common for mixed metal oxides and halides. In this structure A and B are cations of different sizes and X is either an oxide or halide. the structure is built up of a simple cube of A cations with anions in the center o..
The first ionization energies for Ge, As, and Se are 762, 944, and 941kJ/mol, respectively. Explain these values in terms of their electron configurations.
13.00 moles of gas are in a 5.00 L tank at 22.6 C. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a = 2.300 L^2*atm/mol2 and b = 0.0430 L/mol.
Metals ions can also be placed in a spectrochemical series. In this case, larger effective nuclear charges generally lead to larger values for (delta) . Based on this principle, predict a spectrochemical series for the following ions
