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 valid approach? Why or why not? In three to five sentences, explain your reasoning.
Yes, this approach is valid. By performing the reaction in a vacuum chamber, the scientist can prevent any external factors from affecting the reaction, such as changes in pressure or the presence of certain gases. Additionally, measuring the energy absorbed or given off in the reaction can determine if it is endothermic (absorbs energy) or exothermic (releases energy). By controlling the experiment and measuring the energy changes, the scientist can accurately determine the nature and extent of the reaction.
