Question 1 of 254.0 PointsA sample of a gas occupies 1.40 × 103mL at 25°C and 760 mmHg. What volume will it occupy at the same temperature and 380 mmHg? A. 1,400 mLB.2,800 mLC. 2,100 mLD. 1,050 mLE. 700 mL Question 2 of 254.0 Points9.45 g of liquid hexane (C6H14) is introduced into a 10.0 L vessel containing 13.15 atm of oxygen gas at 21ºC and ignited, yielding carbon dioxide and water. If the vessel is then cooled to –10.ºC, what will be the gas pressure inside the vessel?
Question 3 of 254.0 PointsA pressure that will support a column of Hg to a height of 256 mm would support a column of water to what height? The density of mercury is 13.6 g/cm3; the density of water is 1.00 g/cm3 .
Question 4 of 254.0 PointsWhich conditions of P, T, and n, respectively, are most ideal? n n
n n Question 5 of 254.0 PointsGas A and gas B are combined in a flask at initial pressures of 1.0 atm each. The flask is sealed and over time they react to completion to give gas C according to the following chemical equation:2A(g) + B(g) → C(g)Assuming the temperature stays constant, what will be the total pressure in the flask after the reaction goes to completion? A. 0.33 atmB. 0.75 atm
C. 0.50 atmD.1.0 atmE. 0.67 atm
