Which of the following best summarizes a major theme of chemistry?
a. If left alone, natural systems tend to interact to produce lower energy states.
b. If left alone, natural systems tend to interact to produce higher energy states.
c. If left alone, natural systems tend to interact to produce the same energy states.
d. If left alone, natural systems tend not to interact.
Chemistry is the study of all matter. These include anything that has mass, volume, and inertia. Chemistry also include the study of their reactions, and the energy changes that are involved in these reactions.
Answer and Explanation: 1
The answer is a. If left alone, natural systems tend to interact to produce lower energy states.
A major theme of chemistry is the occurrence of chemical reactions among different chemical substances. These reactions or interactions happen because substances or systems want to achieve stability, which is characterized by having a lower energy state. For instance, elements combine together by forming chemical bonds, so they can achieve a more stable, lower energy state.
