9) The value of#H for a system at constant pressure that performs 13 kJ ofpressure-volume work on its surroundings and loses 9 kJ of heat is ______ kJ.
10) Which of the following statements is FALSE?
11) A cylinder of argon gas holds 20.0 L at a temperature of 25°C and a pressure of18,000torr.What volume would the argon from this cylinder occupy at STP?
12) 50.0 mL of 1.00Msodium hydroxide is mixed with 50.0 mL of 1.00Mhydrochloric acid.Each solution is initially at 25.0°C. After they are mixed, the temperature rises to 31.7°C.What is the molar enthalpy change for the neutralization of hydrochloric acid by sodiumhydroxide?
