A mixture of water and graphite is heated to 600 K. When the system comes to equilibrium it contains 0.13 mol of H2, 0.13 mol CO, 0.43 mol of H2O and some graphite. Some O2 is added to the system and a spark is applied so that the H2 reacts completely with the O2. Find the amount of CO in the flask when the system returns the equilibrium

A gas containing only CH4 and N2 is burned with air yielding a flue gas that has an Orsat analysis of CO2:8.7%, CO: 1.0%, O2:3.8%, and N2:86.5%. Calculate the percent excess air used in combustion and the composition of the CH4-N2 mixture.
Consider the combustion of liquid ethanol. a) Write the complete balanced chemical equation for the reaction, including state subscripts. b) Calculate the change in enthalpy per mole of ethanol.
Consider a glass of 218 mL of water at 30°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved. To find the mass of water use the density of water = 1.0 g/mL.
