False. Proprietary name would be equal to the trade name of a drug.
False. A proprietary name is a unique brand name given to a drug by its manufacturer for marketing purposes. It does not describe the chemical structure of the drug.
Congruence.
The official chemical name is exactly actinium.
I think what you're referring to is a 'generic' product. Where it is a medication that performs exactly the same as a branded medicine.
Geographic coordinates, such as latitude and longitude, precisely identify a location on Earth's surface.
Absolute location
As I understand it, a database schema is a physical entity, it describes the structure of exactly how the data is stored and is itself stored by DBMS for reference. Data model, on the other hand, is an abstract representation of database.

A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds.
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
