When a need exist to mention the valence, electrical charge, mass number of an isotope.
subscripts are the cation superscripts are the anian
chemical equations
fe + O2 = feO
The chemical symbol of silver is Ag: chemical symbols are used in chemical formulae and equations.
chemical equations are used to find out how chemical compounds will react with each other since the equations must be balanced. unless you are talking about the chemical name for substances such as sodium chloride is NaCl. water is H2O etc.
In Microsoft Word, chemical equations can be entered using special character menus. For example, subscripts and superscripts can be used to denote isotopes, and arrows can indicate reactions.
subscripts are the cation superscripts are the anian
In chemical symbols, superscripts following the letters tell us the number of charges on an ion.
formulas
(d) apex
Because they are shorter.
It is more simple and practical.
to determine the mole of the atom
Honey hasn't chemical equations.
chemical equations
Chemical equations describe the products and reactants in a chemical reaction.
All of the symbols used in chemical equations are up on the Periodic Table.
