All of the symbols used in chemical equations are up on the periodic table. I hope that helps.


Actually there are a number of additional symbols used besides those found on the periodic table. Some of these include:

(s) means the substance is in a solid state

(g) means the substance is in a gaseous state

(l) means the substance is in a liquid state

(aq) means the substance has been dissolved in an aqueus solution (which is to say, water)

→ means "yields" and is used to indicate the result of the reaction.

↔ means that the reaction is reversible

↑ indicates a change of state (into a gas)

↓ indicates a precipitate formed by a reaction

∆ (over the reaction arrow) indicates the application of heat to the reactants


In addition, other factors may be noted above the reaction arrow such as the specific temperature, the catalyst required, the pressure needed, the application if electricity etc.

Why are chemical formulas and chemical equations used?

Chemical formulas are used because they show the chemical make up of a substance. Chemical equations are used because it is much easier to use symbols as a shorthand way of describing and visualizing a chemical reaction, rather than writing it out in words.

How are abreviations and symbols alike in science?

Abreviations and symbols in science are both used as a shorthand system for frequently referenced concepts in writing. Symbols are used in mathematical equations to stand for constants or variables. As examples:In Chemical reactions: NaCl is table saltIn Chemical equations: 2H2 +O2 -> 2 H2OIn mathematical equations: E=MC^2In science literature: LSD is used in place of lysergic acid diethyl amideAs constants in physics equations: density is replaced by ρ (the lower case Greek letter rho)
