@X@user.full_name@X@ @GMU: A gas mixture contains an unknown amount of CO2 and 0.1740 mol of O2. How many moles of CO2 are there, if the total pressure is 707.52 mm Hg and the partial pressure of CO2 is 299.76 mm Hg?

Which patient is most at increased risk for constipation?

@X@user.full_name@X@ @GMU: Balance the reaction below; determine the sum of the coefficients; this is in a basic solution! Include co-efficients for any unshown species(such as water and hydroxide)._MnO4- + _H2O2 → _MnO2 + _O2

@X@user.full_name@X@ @GMU: A flexible container was filled with NO2 gas at a pressure of 1.74 atm and volume of 18.052 L. What pressure would this gas exert if the volume decreased to 7.49 L? Assume temperature is constant.

@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7086 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 190.85 cm lower than the level in the arm connected to the gas sample? The atmospheric pressure reading is 759.96 mm Hg.

@X@user.full_name@X@ @GMU: A gas mixture contains 0.1137 mol of Ne and 0.1516 mol of H2S. What is the partial pressure of Ne, if the total pressure is 385.97 mm Hg?

@X@user.full_name@X@ @GMU: Which of the following is an oxidation process?

@X@user.full_name@X@ @GMU: The density of a particular gas is 1.8474 g/L at 765.29 mm Hg and 19.75 °C. What is the molecular mass of the gas?

@X@user.full_name@X@ @GMU: A compound contains only rubidium and bromine. A sample weighing 4.72 g of this compound contained 2.44 g of rubidium. How many grams of bromine would there be in another sample of this compound containing 6.37 g of rubidium?

@X@user.full_name@X@ @GMU: The density of a particular gas is 1.7197 g/L at 715.02 mm Hg and 20.84 °C. Which gas is it?
