A scientist wants to perform a reaction in a vacuum chamber to control the experiment as much as possible and to prevent other
variables from impacting the reaction. The scientist is trying to determine if the reaction is endothermic or exothermic and measure how
much energy is absorbed or given off. Is this a sound approach? Why or why not? In three to five sentences, explain your reasoning.

Yes, it is a sound approach because a vacuum system is an isolated system.

Isolated system

An isolated system is one in which neither energy nor mass can be exchanged with the surrounding.

In a vacuum, mass and energy may not be exchanged with the surroundings. In other words, a vacuum is a good system for measuring the total energy of a reaction.

Thus, it will be possible for the scientist to measure the energy of the reaction and determine whether is endothermic or exothermic.
