5. Hydrogen gas reacts with oxygen to form water. 2 H2(g) + O2(g) → 2 H2O(g), AH=-483.5kJ Determine the mass of oxygen and hydrogen needed to produce 483 J of heat without leaving any reactant. [0.5] 6. Use standard enthalpies of formation from Appendix II.B from at the end of the textbook to determine AHºrxn for the combustion reaction of hexane (C6H14). [0.5]
Hydrogen gas, H2, and oxygen gas, O2, can be reacted to form liquid water. If 2.00 g hydrogen gas and 17.20 g oxygen gas are reacted in a 1.500 L flask at 25.0 °C, calculate the total gas pressure (atm) in the flask at 25 °C. The vapor pressure of water is 23.8 mm Hg. Stoichiometry is involved in this question. Total gas pressure:
