@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: What is the correct name for V2O3?

@X@user.full_name@X@ @GMU: Which of the answers below is the correct representation according to the shorthand method of the following cell?Ni2+(aq) + Mg(s) → Ni(s) + Mg2+(aq)

@X@user.full_name@X@ @GMU: What is Kp for the reaction below, if Kc = 1.03e-3 at 256.4°C?3A(s) + 2B(g) → 5C(g)

The resting membrane potential in animal cells largely depends on nongated channels for which one of the following ions?

@X@user.full_name@X@ @GMU: What is the correct name for FeBr3?

@X@user.full_name@X@ @GMU: What is the correct name for FeF3?

@X@user.full_name@X@ @GMU: What is the total concentration of ions in a solution consisting of 0.1973 M NaCl?

@X@user.full_name@X@ @GMU: Closed-tube manometers work exactly as barometers except by connecting them to a container its pressure can be measured. Assume you have a closed-ended manometer filled with an oil having a density of 0.7546 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure if the height of the oil column is 917.71 cm?

@X@user.full_name@X@ @GMU: Balance the reaction below; determine the sum of the coefficients; this is in an acidic solution! Include co-efficients for any unshown species (such as water and H+)._MnO4- + _Ag → _Mn2+ + _Ag+
