state the difference between nuclear and chemical change
Answers
Answer:
nuclear change involves change at the nuclear level and results in new elements (different from the reactant/s).
A chemical change generates new substances, but new elements are not generated.
chemical changes are observed (typically) by the generation of gases, heat, etc. (Apart from the formation of new chemical species).
Explanation:
An example of nuclear change is the radioactivity of uranium 238. When this element undergoes radioactive decay, it transforms into thorium-234 along with generating an alpha particle
An example of a chemical change is the breakdown of glucose in the presence of oxygen, where the end product is carbon dioxide and water. Here, the result is a new chemical species (CO2 and water) but no elemental changes are there.
hope this helps
