CHAPTER 8: CHEMICAL REACTIONS
8.1 Reaction Rates
chemical kinetics: study of the factors affecting the rates of chemical reactions
rate = moles of product appearing / elapsed time
-collisions must occur
rate of collisions depends on:
concentration of r
CHAPTER 7 SOLUTION
Most chemical reactions take place in a solution
7.1 General Aspects of Solution Formation
solute: substance in smaller amount
solvent: substance in larger amount
*there is a limit to the amount of solid solute that can be dissolved in
7.10 Insolubility can result in a Chemical Reaction
-complete ionic equation includes ions that are unaltered on both sides of the equation
-net ionic equation: includes only ions that participate in the reaction
-spectator ions: the ions left out of the
