In chemistry, S2 typically refers to a sulfide ion, which is a negatively charged ion composed of two atoms of sulfur. Sulfide ions are common in compounds such as hydrogen sulfide (H2S) and metal sulfides (e.g. FeS, ZnS).
Ferrous is the traditional name of the iron (II) ion. (Fe 2+) The formula for ferrous sulfide is FeS since sulfur has a charge of -2.
The chemical formula for lithium is Li. The chemical formula for sulfide ion is S2-. Therefore, the chemical formula for lithium sulfide would be Li2S.
The symbol for sulfide, one of the many ions, is S2-.
A mole of sulfur (S) contains approximately 6.022 x 10^23 sulfur atoms. The molecular weight of sulfur (S) is about 32 g/mol. Therefore, a mole of sulfur (S2) would weigh 64 grams (32 g/mol x 2).
It is not possible to determine which one is larger in size without more context or information about what S and S2 refer to. Size comparison between two entities requires specific measurements or criteria to make a valid comparison.

Salts are the products of the reactions between acids and bases.
Base is a solution that have ph over 7 and can accept hydrogen ions.
When mercury is found in an elemental form, it means that it exists in its pure, uncombined state as a single atom or a molecule of mercury. Elemental mercury is a liquid at room temperature and is known for its unique properties, such as being a good conductor of electricity.

The sample mean is distributed with the same mean as the popualtion mean. If the popolation variance is s2 then the sample mean has a variance is s2/n. As n increases, the distribution of the sample mean gets closer to a Gaussian - ie Normal - distribution. This is the basis of the Central Limit Theorem which is important for hypothesis testing.
