To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored.

A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. An empirical formula gives the simplest, whole-number ratio of atoms in a compound. A structural formula indicates the bonding arrangement of the atoms in the molecule.

Here's a brief tutorial about nuclear symbols. First, an example of a nuclear symbol: 6 14 C. Make sure to remember that the lower number is the atomic number and the upper number is the mass number. atomic number mass number element symbol. Here's another nuclear symbol: 92 238 U. That 92 is the atomic number, which is the number of protons.

Chemical reactions are described by chemical equations.A chemical equation represents, with symbols and formulas, the identities and relative amounts of the reactants and products in a chemical reaction. For example, the following chemical equation shows that the reactant ammonium dichromate yields the products nitrogen, chromium(III) oxide ...
The physical states of reactants and products in chemical equations very often are indicated with a parenthetical abbreviation following the formulas. Common abbreviations include s for solids, l for liquids, g for gases, and aq for substances dissolved in water (aqueous solutions, as introduced in the preceding chapter).
