You place 1.85 grams of wood in a vessel with 9.45 grams of air and seal the vessel. Then you heat the vessel strongly so that the wood burns. In burning, the wood yields ash and gases. After the experiment, you weigh the ash and find that its mass is 0.28 grams. What is the mass of the gases in the vessel at the end of the experiment?

You have been asked by the local coal power plant to conduct some carbon sequestration experiments aimed at determiing the efficacy of the local crystalline basement rocks to sequester CO2. They have asked you to determine how much carbonate forms when you react 10 grams of gabbro with CO2 at 150 degres C and 1kbar. You go to your lab and find a 750 ml pressure vessel that is rated to 10kbar pressure.

a.) how many grams of dry ice should you add to the vessel along with the 10 grams of gabbro to reach 1kbar of pressure at 150 degrees C?

b.) with this mass of CO2 in the vessel, what is the maximum temperature the filled pressure vessel can reach before exceeding its pressure rating?

Problem 9.128

An empty 4.25 L steel vessel is filled with 1.15 atm of CH4(g) and 4.60 atm of O2(g) at 300 âC. A spark causes the CH4 to burn completely, according to the equation:
CH4(g)+2O2(g)âCO2(g)+2H2O(g) ÎHâ = -802kJ

Part A

What mass of CO2(g) is produced in the reaction?

mCO2=4.57

Part B

What is the final temperature inside the vessel after combustion, assuming that the steel vessel has a mass of 12.475 kg , the mixture of gases has an average molar heat capacity of 21J/(molâ âC), and the heat capacity of steel is 0.499J/(gâ âC)?

Part C

What is the partial pressure of CO2(g) in the vessel after combustion?
