| Question | Answer |
|---|---|
| Atom | A basic unit of matter, consisting of a nucleus (that made of neutrons and protons) and surrounded by a cloud of negatively charged electrons |
| Isotopes | are different types of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties |
| Mass Number | is the number that indicates the total number of protons and neutrons in a nucleus |
| A reactor | a container or apparatus in which substances are made to react chemically, especially one in an industrial plant |
| A unit operation | unit operation is one of the basic step in an industrial process, that follows the same physical laws of other steps to archive the overall process |
| Mutation | is a permanent change in the sequence of a gene, which is cause by DNA copying mistakes, exposure to chemicals or radiation, or infection by viruses |
| Condensation | is a fenomenan in which the matter changes from the gaseus phase into a liwuid droplets or solid |
| Liquefaction | is a process by which a substance is transformed into a liquid by cooling or heating |
| Catalysis | is a chemical process in which the rate of chemical reaction changes due to the participation of a catalyst |
