What is true about the value of A) It is greater than zero.
What is true about the value of q? A) It is greater than zero. Answer the following questions about what occurs when the valve between the two bulbs is opened. Use the following to answer questions Consider a gas in a bulb at STP that is connected via a valve to another bulb that is initally evacuated. When 32.0 g of sulfur is burned, 2.96 105 J of energy is released. When 0.500 mol of sulfur is reacted, 148 kJ of energy is released. Given the equation S(s) O2(g) SO2(g), kJ, which of the following statements is(are) true? I. C) the difference in the bond energy in H2O(l) compared to H2O(g). B) the work done in pushing back the atmosphere. For the reaction H2O(l) H2O(g) at 298 K, 1.0 atm, is more positive than 2.5 This quantity of energy can be considered to be A) the heat flow required to maintain a constant temperature. E) At least two of these statements are true. D) The heat of reaction and change in enthalpy can always be used interchangeably. C) A chemist takes the point of view of the surroundings when determining the sign for work or heat. B) In exothermic reactions, the reactants are lower in potential energy than the products. Which of the following statements is(are) true? A) Enthalpy is a state function. Which of the following are state functions? A) work, heat B) work, heat, enthalpy, energy C) enthalpy, energy D) work, heat, enthalpy E) heat, enthalpy, energy 7. Consider the following reaction: 2SO2(g) O2(g) 2SO3(g) kJ Calculate the enthalpy change associated with 23.8 g of SO2 reacting with excess O2. J D) The change in the internal energy for this process is zero. Which statement is true for this process? A) B) The work done in compressing the system must exactly equal the work done the system in the expansion step. J of expansion work, and then return the system to its initial state cooling and compression. Suppose you add 45 J of heat to a system, let it do 10. B) The system does work on the surroundings. Which of the following statements is true? A) Heat flows from the surroundings to the system. For a particular process q kJ and w 25 kJ. Calculate for a system that releases 24 J of heat while 57 J of work is done on it. One mole of an ideal gas is expanded from a volume of 1.50 L to a volume of 10.18 L against a constant external pressure of 1.03 atm.
