6. GENERALIZATION Direction: MODIFIED TRUE or FALSE: Write the word TRUE if the statement is correct and if not, underline the word or statement that sentence incorrect and write the correct answer on your answer sheet. Write your answer on a separate sheet of paper. swer 1. The law of conservation of energy states that energy can either be created or destroyed. 2. A closed system is a system that has external interactions, such as energy transfers into or out of the system boundary. 3. According to the first law of thermodynamics, when heat enters or leaves a system, the system gains or loses an amount of energy equal to the amount of heat transferred. 4. A measure of energy transfer that occurs when an object is moved over a distance by an external force is known as heat. 5. The transformation of chemical energy into kinetic and heat energy by a car engine is a manifestation of the first law of thermodynamics. 6. An open system could not create or destroy energy. 7. Energy is a…

Homework • Unanswered Which of the following statements about microstates, macrostates, and probability are true? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V The more microstates are associated with a macrostate, the more probable that macrostate is. b The macrostate is the measured state of the system. A system is in multiple microstates at the same time. d The microstate a system is in changes as particles move and or energy is transferred between particles.

A chemist fills a reaction vessel with 3.61 atm nitrogen (N,) gas, 8.64 atm oxygen (0,) gas, and 6.55 atm nitrogen monoxide (NO) gas at a temperature of 25.0° C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: N,(g) + O,(g) = 2NO (g) Use the thermodynamic information in the ALEKS Data tab.
