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.
