Across
  1. 3. a substance that decreases the rate of or stops completely a chemical reaction.
  2. 6. a measure of the amount of dissolved substance contained per unit of volume.
  3. 7. a principle stating that if a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.
  4. 8. rate of a chemical reaction is defined as the change in the concentration of a reactant or a product over the change in time,
  5. 10. that is a measure of the energy that is not available for work
  6. 13. a measure of the warmth or coldness of an object or substance
  7. 15. substance obtained from another substance through chemical change.
  8. 17. can go in both directions; reactants can turn into products, and products can turn back into reactants
  9. 18. any substance that undergoes a chemical change in a given reaction.
  10. 20. chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.
  11. 21. a type of chemical reaction in which one reactant yields two or more products.
  12. 22. ubstance or mixture of compounds that, added to a solution, is capable of neutralizing both acids and bases without appreciably changing the original acidity or alkalinity of the solution.
Down
  1. 1. the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
  2. 2. the surface area of a substance generally increases the rate of a chemical reaction.
  3. 4. an electron of an atom, located in the outermost shell (valence shell) of the atom, that can be transferred to or shared with another atom.
  4. 5. a reaction in which one element is substituted for another element in a compound.
  5. 9. the forming or building of a more complex substance or compound from elements or simpler compounds.
  6. 11. a substance that causes or accelerates a chemical reaction without itself being affected.
  7. 12. a force exerted by the substance per unit area on another substance
  8. 14. the structure that results in the maximum energy point along the reaction path.
  9. 16. hemical combination attended by production of heat and light.
  10. 19. the loss of electrons during a reaction by a molecule, atom or ion
  11. 23. a thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system
