Please answer all three parts and show work. Thank you!
1. An ideal gas assumes molecules are point particles and do not interact with each other. In reality, molecules occupy space! To correct for this, the ideal gas equation of state is adjusted to take the volume occupied by the molecules into account for a real gas: PV = nRT or P = nRTV is modified to P = nRT/(V-nb) (IDEAL GAS) (REAL GAS Where "b" is related to the...

1. Combustion. Balance the Equation below for the combustion of n-butane. Show your work. Then, calculate the reaction enthalpy (per mol butane) at standard temperature and pressure, Allar for two cases: i) using liquid water; and ii) using water vapor. Show your work. Why are the two different and what do they mean? Is the reaction exothermic or endothermic?
