please show me how you got the answer
For a newly discovered chemical compound, it was determined that the vapor pressure can be estimated with the following equation over a range of temperatures that includes the compound's boiling point: = exp(-4 + B), where A = 4,000 K and B = 20 Р Calculate the molar enthalpy of vaporization for this compound. You can assume ideal gas behavior of the vapor. (As an approximation for the gas constant, you can...

Consider the thermochemical equation below. 4Na(s) + O2(g) → 2 Na2O(s) AH = -828 kJ/mol A. Which reactant is the limiting reactant if 30.0 g of sodium is reacted with 12.0 L of oxygen gas at 1525 torr and 285 K? You must explain how you determined the limiting reactant for full credit (10 points) Answer: Na is the limiting reactant (Explanation omitted)...

Please show work! I've tried this problem a few times, but seem
to be going wrong somewhere. The answer should be 366 kJ/mol, but I
do not understand how to arrive at that solution. Thank you!
