Study Notes
Chemical Reactions
- Chemical reactions involve reactants changing composition to form new substances called products.
- Some reactions require specific conditions or catalysts to proceed.
- A catalyst aids reaction but isn't consumed or altered.
Representing Chemical Equations
- Chemical equations can be represented in three ways: word equation, skeleton equation and balanced equation.
Word Equations
- Word equations use the names of reactants and products, similar to standard chemical format.
Skeleton Chemical Equations
- Skeleton equations use chemical formulas of reactants and products.
- No coefficients are used for balancing.
- States of matter (solid, liquid, gas, aqueous) of reactants/products are included after formulas.
