1. 11.1 Describing Chemical Reactions Explain how to write a word equation.
Describe how to write a skeleton equation.
List the steps for writing a complete balanced chemical equation.
2. Writing Chemical Equations process by which one or more substances are changed into 1 or more DIFFERENT substances
original substances = reactants
resulting substances = products
chemical reactions are represented by chemical equations
3. Word Equations Must contain only known facts
Must contain correct names (don’t forget diatomic molecules)
reactants ? products
word equation: names of reactants and products with symbols for what is occurring
reading equations example reactants on left of arrow
products on right of arrow
arrow means produces or yieldsreactants on left of arrow
products on right of arrow
arrow means produces or yields
