  1. 4. release energy in the form of heat and light, so they are exothermic
  2. 8. is a type of reaction that occurs when the cations and anions switch between two reactants to form new products
  3. 11. are molecules made of two atoms chemically bonded together. The atoms can be of the same element
  4. 12. Substances initially present in a chemical reaction that are consumed during the reaction to make products
  5. 13. is an insoluble solid that emerges from a liquid solution. The emergence of the insoluble solid from solution
  6. 15. A representation of a chemical reaction using symbols of the elements to indicate the amount of substance, usually in moles, of each reactant and product
  7. 17. A number or symbol multiplied with a variable or an unknown quantity in an algebraic term
  8. 18. Also referred to as reaction yield, is the amount of product obtained in a chemical reaction. The absolute yield can be given as the weight in grams or in moles
  9. 19. In chemical formulas the number of atoms in a molecule
  10. 20. A decomposition reaction is a type of chemical reaction where one reactant yields two or more products.

  1. 1. A process in which atoms of the same or different elements rearrange themselves to form a new substance
  2. 2. A combustion reaction is a type of chemical reaction where a compound and an oxidant is reacted to produce heat and a new product.
  3. 3. a chemical reaction in which an acid and a base interact with the formation of a salt;with strong acids and bases the essential reaction is the combination of hydrogen ions with hydroxyl ions to form water
  4. 5. State of matter consisting of particles that have neither a defined volume nor defined shape
  5. 6. is a substance formed when two or more chemical elements are chemically bonded together
  6. 7. Also called single-replacement reaction, is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another that is, one element is replaced by another in a compound.
  7. 9. solution is a solution in which the solvent is water
  8. 10. Tend to be packed together much closer than the other particles
  9. 14. The substances that result from this recombination of atoms
  10. 16. Form of matter between a gas and a solid that has a definite volume, but no definite shape
