NaCl- Endothermic NaNO3- Endothermic CaCl2- Exothermic CuSO4 - Endothermic NH4Cl- Endothermic 2. I wouldn’t want to sell a cold pack made with compound x because the temperature should continue to decrease for the best results, if temperature remains the same for 24 minutes; it is not an effective cold pack. Another reason why I wouldn’t want to sell a cold pack made with compound x because 10g is a great amount and when comparing to other salts, which are more effective in less than 10g, there are better salts that can be used.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
