- 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.arrow_forwardSolar energy is: O the energy stored within the structural units of chemical substances.
