Yes, chemical elements are substances.
Tea is a physical substance and therefore can be considered a matter. It consists of various compounds and elements that make up its composition.
The oxidation number of an elementary substance is zero because there is no transfer of electrons between atoms of the same element in a compound. Each atom in an elementary substance is considered to have an oxidation number of zero.
Yes. Sodium benzoate is a compound and thus a pure substance.
HCl is considered an acidic substance.
Coffee is considered to be an acidic substance.
Water is pure substance because it is two elements chemically combined, rather than just mixed.

No, sertraline is not considered a controlled substance.
An element is a pured substance and a pure substance is a material
The oxidation number of an elementary substance is zero because there is no transfer of electrons between atoms of the same element in a compound. Each atom in an elementary substance is considered to have an oxidation number of zero.
Yes. Sodium benzoate is a compound and thus a pure substance.
No, a magnet is not considered a substance of chemicals. It is a material that generates a magnetic field due to the alignment of its atoms. Chemical substances are composed of specific elements in defined ratios.
