@X@user.full_name@X@ @GMU: Draw the lewis dot structure of CO2. How many lone-pairs of electrons (first) and bonding pairs of electrons exist on the molecule CO2?

@X@user.full_name@X@ @GMU: A flexible container was filled with 0.1146 mol of NH3 at a volume of 15.39 L. How many liters of this gas would there be if the number of moles increased to 0.1795 mol? Assume pressure is constant.

@X@user.full_name@X@ @GMU: A flexible container was filled with 0.1735 mol of N2O4 at a volume of 15.11 L. How many moles of this gas would there be if the volume increased to 23.44 L? Assume pressure is constant.

@X@user.full_name@X@ @GMU: A gas mixture contained 43.60% by weight HF and 56.40% N2O. What was the mole fraction of HF?

@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7701 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 135.26 cm lower than the level in the arm connected to the gas sample? The atmospheric pressure reading is 770.03 mm Hg.

@X@user.full_name@X@ @GMU: A flexible container was filled with CO2 gas at a pressure of 1.054 atm and volume of 19.845 L. What volume would this same gas occupy if the pressure increased to 2.347 atm? Assume temperature is constant.

@X@user.full_name@X@ @GMU: How much work has been done when the volume of a gas changes from 10.82 L to 20.69 L at a constant pressure of 1.829 atm and temperature?

@X@user.full_name@X@ @GMU: What is the average speed of CO molecules (atoms) at 25.00 °C?

@X@user.full_name@X@ @GMU: What is the average speed of O3 molecules (atoms) at 25.00 °C?

@X@user.full_name@X@ @GMU: A flexible container was filled with CO2 gas at a pressure of 1.493 atm and volume of 18.164 L. What volume would this same gas occupy if the pressure increased to 2.744 atm? Assume temperature is constant.
