How would you define the flashlight as a system? What are its inputs and outputs? What are the parts of the system?

Olá. porque a reação na temperatura é muito rapida a do copo : )

1.75 is the weight of one medium egg

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
