Chemical-reaction equation {chemical equation} uses molecule chemical formulas and special symbols. Reactant formulas are on left, and product formulas are on right.
direction
Horizontal arrow pointing right separates reactants from products. Delta symbol means to add heat. hv symbol means to add light.
terms
Plus signs separate molecules.
symbols
Up arrow (^) at formula right indicates that reaction produces gas. Down arrow at formula right indicates that reaction precipitates solid. The letter s at formula right means that reagent is solid. The letter l at formula right means that reagent is liquid. The letter g at formula right means that reagent is gas. The letters aq at formula right mean that reagent is aqueous.
balance
Atoms on chemical-reaction left must also be on right, so both sides have same atom numbers and types {conservation of mass, chemical equation}.
