Presentation Transcript

    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
