Unit 7 – Chemical Reactions: Particles and Energy
This unit aligns with textbook chapter 9. Additional reasources are listed below.
Test preparation
u7 test- classifying chemical reactions, balancing reactions, describing energy transfer in chemical reactions. Practice describing reactions in words (macro and micro scale), symbols, particle diagrams, Given any representation of a chemical reaction, students should be able to produce any other represenation. Be sure to show ions correctly in particle diagrams, make correct use of the terms "formula units" "molecules" "atoms" or "ions" when describing reactions at particle level. Review also from unit 5 the steps to calculate an empirical formula from %composition, or from other mass data.
