What mass of AgCl will dissolve in 1.00 L of water containing 0.088 moles of NaCl? Kspof AgCl is1.7x 10-10. Report your results as a -log value, for example if your answer was 5.13 x 10-7, -log 5.13 x 10-7= 6.285.
what is the entropy change for freezing 4.25 g of c2h5oh at 158.7 k? h -4600 jmol.answer in units of
Calculate the heat released when 2.58 L of Cl2(g) with a density of 1.88 g/L reacts with an excess of sodium metal at 25°C and 1 atm to form sodium chloride.
Explain the resolution limit of a microscope is roughly equal to the wavelength of light utilized in producing the image. Electron microscopes utilized an electron beam in place of photons to produce much higher resolution images, about 0.16 in mo..
