By the end of this unit students will be able to:

  • Explain the energy content of a chemical reaction.
  • Analyze the evidence of chemical change.
  • Analyze the law of conservation of matter and how it applies to various types of chemical equations (synthesis, decomposition, single replacement, double replacement, and combustion).
  • Analyze the stoichiometric relationships inherent in a chemical reaction.
  • Analyze quantitatively the composition of a substance (empirical formula, molecular formula, percent composition, and hydrates).
