What are polymers? how are polymers classified based on their source?

A polymer is often known as very large molecules. They don't just have random molecules in them, they have synthetic and natural molecules.

Polymers are classified by source in many ways. You have natural polymers, which are in nature or come from other natural polymers, Synthetic polymers via humans or the inside of a paper package. Lastly there are Semi-Synthetic polymers, which are made mostly in the lab.

ur answer would be b hope i let me know if it is right

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
