CHAPTER 8 - CHEMICAL REACTIONS - textbook pages 252 - 282
Main Ideas:
Chemical reactions have physical indicators.
Chemical equations must satisfy the law of conservation of mass.
Chemical equations show relative amounts, masses, and progression of chemical reactions.
Chemical equations use chemical formulas with coefficients to show how a reaction satisfies the law of conservation of mass.
Key terms:
chemical equation
precipitation
coefficient
word equation
formula equation
