Study Notes
State Symbols in Chemical Equations
- State symbols indicate the physical state of reactants and products in a chemical reaction.
- The physical states include solid (s), liquid (l), gas (g), and aqueous (aq) for dissolved substances in water.
- Example: 2Na(s) + 2H₂O(l) → 2NaOH(aq) + H₂(g) shows sodium (solid), water (liquid), sodium hydroxide (aqueous), and hydrogen (gas) in this reaction.
Organic Compound Decomposition
- An example of an organic compound decomposition is C₆H₅N₂Cl(aq) → C₆H₅Cl(l) + N₂(g).
- The reactant (C₆H₅N₂Cl) is aqueous (dissolved in water). The product (C₆H₅Cl) is liquid, and the product (N₂) is a gas.
