A scientist is trying to determine if a reaction is endothermic or exothermic and measure how much energy is absorbed or given off. The scientist plans to perform the reaction in a vacuum chamber to control the experiment as much as possible and to prevent other variables from impacting the reaction. A vacuum chamber is an enclosed container with all air removed. Is this a valid approach? Why or why not? In three to five sentences, explain your reasoning.
Yes, performing the reaction in a vacuum chamber is a valid approach to control the experiment and prevent other variables from impacting the reaction. In a vacuum, there is no air to impact the reaction, which ensures that only the reactants and products are involved. This allows for accurate measurement and determination of the energy absorbed or given off during the reaction, as there are no external factors influencing the outcome. Additionally, by removing air, potential side reactions or complications that may arise due to air molecules are eliminated, providing a more controlled and reliable environment for the reaction.
