Unit 7 – Chemical Reactions: Particles and EnergyThis unit aligns with textbook chapter 9. Additional reasources are listed below.chemteam info has a whole section devoted to reaction types and balancing.Test preparationu7 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 representation. 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.3. Worksheet 1: Balancing Equations
