@X@user.full_name@X@ @GMU: What is the standard cell voltage at 25.0oC for the reverse of the reaction below?Hg2+(aq) + Cu(s) → Hg(l) + Cu2+(aq) K = 1.78e17

@X@user.full_name@X@ @GMU: What is the balanced reaction for the following galvanic cell?Sn(s)| Sn2+(aq) || Cu2+(aq) | Cu(s)

@X@user.full_name@X@ @GMU: Kaolinite, a clay mineral with the formula Al4Si4O10(OH)8, is produced naturally by the chemical weathering of aluminum silicate minerals like feldspar (granite). Kaolinite is used industrially as filler in slick-paper for magazines and as a raw material for ceramics. How many grams of oxygen are present in 10.77 g of kaolinite?

@X@user.full_name@X@ @GMU: A flexible container was filled with CH4 gas at a pressure of 1.07 atm and volume of 15.018 L. What pressure would this gas exert if the volume increased to 25.44 L? Assume temperature is constant.

@X@user.full_name@X@ @GMU: What is the energy of photons with a frequency of 8.464e+14 s-1? Remember Planck’s constant is 6.626×10-34 J×s

@X@user.full_name@X@ @GMU: What is the total concentration of ions in a solution consisting of 0.5236 M KBr?

@X@user.full_name@X@ @GMU: What is the standard cell voltage at 25.0oC for the reverse of the reaction below?Sn4+(aq) + Cd(s) → Sn2+(aq) + Cd2+(aq) K = 4.01e18

@X@user.full_name@X@ @GMU: The density of a particular gas is 0.6182 g/L at 695.89 mm Hg and 34.26 °C. Which gas is it?
