If we run an experiment in which two substances chemically react in a closed system and then we run the same experiment in an open system, then the masses of the products in each experiment will be different because the open system allows the interchange of matter and energy with the media.
<h3>What is an open system?</h3>
An open system is an interrelated group pf parts that work together to interchange matter and energy with the surrounding environment, while a closed system does not generate an exchange of matter and energy.
Therefore, with this data, we can see that an open system interchange energy and matter with the environment, while closes systems do it.
