Suppose that 10 moles of hydrogen gas, with an entropy at 300 K and 1 bar pressure of 131 J/(mole K), is squeezed into a solid where most of this entropy is lost. How much heat is evolved

c u c l 2 + 2 n a n o 3 → c u ( n o 3 ) 2 + 2 n a c l

  long weird answer but i hope this works

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
