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

  • Recognize the physical indicators of chemical reactions.
  • Write chemical equations using the appropriate nomenclature and symbols.
  • Satisfy the Law of Conservation of Mass while balancing chemical equations.
  • Classify reactions (synthesis, decomposition, single-displacement, double-displacement, and combustion).
  • Predict the products of a synthesis, decomposition, and combustion reactions. 
  • Use the activity series to predict the products of a single-displacement reaction.
  • Use the solubility rules to determine the solubility of the products of a double-displacement reaction.
  • Define endothermic and exothermic.
  • Describe the factors that change the rate of the reaction.
