@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7215 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure in atmospheres if the level of the arm open to the atmosphere is 158.46 cm higher than the level in the arm connected to the gas sample? The atmospheric pressure reading is 726.52 mm Hg.

@X@user.full_name@X@ @GMU: ACS-Using the given rate data what is the correct rate law for the reaction below?H2 + Br2 ⇋ 2HBr  Exp [H2]o [Br2]o Initial Rates, Ms-1 1 0.117 0.117 8.01e-1 2 0.234 0.117 3.20 3 0.234 0.184 5.04

What is the correct equilibrium constant expression, Kc, for the following reaction?2CH4(g) + 3O2(g) → 2CO(g) + 4H2O(g)

@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 0.7939 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 1088.93 cm?

@X@user.full_name@X@ @GMU: A compound contains only magnesium and fluorine. A sample weighing 5.56 g of this compound contained 2.17 g of magnesium. How many grams of fluorine would there be in another sample of this compound containing 4.16 g of magnesium?

Which of the following conditions will cause equilibrium to shift to the rightFeO(s) + CO(g) ⇋ Fe(s) + CO2(g)

@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: 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?
