Question 19 19. A sample of has the pressure of 2.21 atm. at 22°C. Calculate the new pressure at the temperature of 105°C. 1.53 atm. 2.83 atm. 9.01 atm. 20.8 atm. 16. Consider the following chemical reaction: CaHelg) + 6O2(g) --------- -> 4CO2(g) + 4H2O(g) 3.50 g C4H8 (8) is mixed with 0.250 moles of of oxygen gas, Calculate the grams of carbon dioxide. molar masses: C4H8 - 56.10 g/mole, and CO2=44.01 g/mole 0.3213 11.08 5.128 7.34g
Question 14 2 pts Consider the following chemical equation: 2PbO2 2P60 + O2 If the reaction described by this chemical equation started with 5.77 grams of PbO2 and resulted in 0.331 grams of O2, what is the percent yield of O2? The molar masses of the compounds in the reaction are as follows: 1 mole of PbO2 = 239.20 g 1 mole of PbO = 223.20 g 1 mole O2 = 32.00 g 85.8% none of these answers are correct...
7. A. Balance the following combustion reaction of pentane(CsH12): (16 pts) CsH12 + O2(g) + CO2(g) + H2O(9) B. If I begin with 6.85 grams of pentane how many grams of CO2 will theoretically be produced? C. What would the temperature(K) of CO2 gas be if the amount produced in Part B had a pressure of 1.55 atm. and occupied 27.3 liters?
Question 16 1 pts Consider the following endothermic reaction at equilibrium: 2NH3(e) <--> N2(g) + 3H) Le Chatelier's principle predicts that adding N2 (g) to the system at equilibrium will result in a decrease in the concentration of NH3 (8) a decrease in the concentration of H2(g) an increase in the value of the equilibrium constant a lower partial pressure of N2 removal of all of the H2(g)
Question 16 4 pts Consider the following reversible reaction at equilibrium: 2 NO(g) + O2(8) =2 NO2(g). If oxygen gas is added to the reaction vessel, the equilibrium will shift to the left. True False
