  1. 2. Two ionic COMPOUNDS swap metals to form two NEW ionic compounds
  2. 4. The final substance(s) are called
  3. 6. the SPEED at which a chemical REACTION occurs
  4. 7. HIGH blank of reactants SPEEDS UP the reaction
  5. 10. Chemical properties can only be observed during
  6. 11. One COMPOUND breaks down into two or more SUBSTANCES
  7. 12. chemical reactions will happen FASTER if there is MORE blank available
  8. 14. INCREASING the blank provides particles with MORE energy, SPEEDING UP the reaction
  9. 16. If a reaction ABSORBS energy from the surroundings it is considered
Down
  1. 1. If a reaction RELEASES energy into the surroundings is is considered
