Final answer:
Combustion reactions produce heat and light and should be conducted in well-ventilated areas to prevent the accumulation of harmful gases like carbon monoxide.
Explanation:
Combustion reactions are reactions where a substance reacts with oxygen gas, releasing energy in the form of light and heat. In a typical combustion reaction, such as the combustion of methane, the products formed include carbon dioxide and water vapor. Knowing that combustion reactions release heat and light, it is crucial to ensure that these reactions take place in well-ventilated areas to prevent the accumulation of potentially harmful gases like carbon monoxide.
