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
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 40 L of propane (C3H8) at 25°C and 0.94 atm is to react, how much heat must be supplied? 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)...

38. Calculate the maximum work that could be obtained if 2.00 mol of an ideal gas, initially at STP, is allowed to expand to 100 L isothermally. Answer-36.0 L-atm 39. If 5.00 mol of an ideal gas is heated at constant pressure from 300 K to 500 K, how much work is done by the expansion of the gas?...
Some scientists believe that coronavirus (Covid-19) can not tolerate high temperatures. They say that keeping the food in hot water (above 70 °C) for at least 5 minutes will make the food safer compared to the uncooked food. a) Calculate the heat, in kilojoules, needed to prepare 10 L of hot liquid water at 75 °C if the initial temperature of water is 20 °C? b) A minimum of how many grams of isooctane (C3H18) must be burned to provide...
