The reactions of hydrocarbons are often studied in the petroleum industry. One such reaction is 2C3H8(g) → C6H6(ℓ) + 5H2(g) with ΔH° = 698 kJ. If 30 L of propane (C3H8) at 25°C and 0.90 atm is to react, how much heat must be supplied (in KJ)? R = 0.08214 L atm mol-1 K-1

In the chemistry lab, one often has to work with very reactive metals such as sodium and lithium. Unfortunately, these same metals can react vigorously with water or oxygen and cause fires. Given the following information: AH (kJ/mol) Li20(s) -597.9 Na20(s) -416 K20(s) -361 CO(9) -110.5 H20(1) -286 CCl4(1) -135 LICI(S) -409 KCI(S) -436 AH (kJ/mol) Li+ (aq) -278.5 Na+ (aq) -240 K+ (aq) -251 CO2(9) -393.5 OH(aq) -230 SiO2(s) -911 NaCl(s) -411 ci(aq)...
