A 3.89 g sample of anthracene (formula C14H10), is mixed with 26.76 atm of O2 in a 7.65x10-1 L combustion chamber at 224.05 C. The combustion reaction to CO2 and H2O is initiated and the vessel is cooled back to 224.05 C. Report all answers to two decimal places in standard notation (i.e. 1.23 atm). 1. What is Pcoz (in atm) in the combustion chamber assuming the reaction goes to completion? Assume all water is water vapour and that the volume of the system does not change. Submit Answer Tries 0/99 2. What is Poz (in atm) in the combustion chamber after the reaction goes to completion? Submit Answer Tries 0/99 A 1.09x10-1 g sample of CO2 and a 1.19x10-1 g sample of H2O react in a closed 4.81 L container at 427 K, according to the following balanced chemical equation: CO2(g) + 2H2O(1) CH4(9) + 2O2(g) Calculate the PCH, (in atm) in the container after the reaction has gone to completion.
