Question

chemical formula?????

Answer 1

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. These are limited to a single typographic line of symbols, which may include subscripts and superscripts. A chemical formula is not a chemical name, and it contains no words. Although a chemical formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula. Chemical formulas can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than are chemical names and structural formulas.

Answer 2

Explanation:

Chemical formula is a representation of a compound that gives the number of atoms and types of atoms in a compound.

The type of atom is represented by chemical symbols.

The number of each type of atom is represented by a subscript.

When there is only one atom of an element present in a compound, no subscript is needed.
