@X@user.full_name@X@ @GMU: A gas mixture contains an unknown amount of CH4 and 0.0907 mol of HCN. How many moles of CH4 are there, if the total pressure is 692.06 mm Hg and the partial pressure of CH4 is 418.25 mm Hg?

@X@user.full_name@X@ @GMU: ACS-What is ΔG° for the reaction below, if ΔH° = 98.80 kJ, ΔS° = 141.500 J/KFe2O3(s) + 3H2(g) → 2Fe(s) + 3H2O(g)

What type of anxiety describes a “checker”?

@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 16.11 g of kaolinite?

@X@user.full_name@X@ @GMU: What is the free energy change at 25°C for the reaction below, if ΔGfo(CH4(g) = -50.790 kJ/mol, ΔGfo(C2H2(g)) is 209.214 kJ/mol.C2H2(g) + 3H2(g) → 2CH4(g)

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 11.92 g of kaolinite?

@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 0.7763 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 1135.17 cm?
