What's is the concentration of silver ions in a saturated solution of silver carbonate? The k^sp of Ag2CO3 is 8.1x10^ -12. Is the answer 5.88x10^-8? I have a test tomorrow and I really need to make sure I'm doing these problems right, but I feel like I am not.
Calculate the concentration of bromocresol green (BG) indicator It says that Molar absorptivity = Absorbance at a wavelength/ concentration of BG indicator I am having trouble calculating the concentration of BG. Other info: Stock solution of BG = 80.0 mg/L and molar mass = 69...
Four particles have free access to distribute into four different energy levels 0,5,10, and 20J. If these four particles are to create two macrostates having total energies 10J and 40J, which macrostate has more entropy?
Suppose you do not know the enthalpy of decomposition of the process: CaCO3 = CaO + CO2 Explain in terms of thermodynamic parameters why heating to a high temperature might turn this decomposition to a spontaneous process.
Mopping the floor in a dry weather makes the floor dry quickly although detlaG0 for the water vaporization at room temperature is positive. Explain.
