  1. 1. new substances produced in a chemical reaction
  2. 3. base indicator a substance that changes color when added to an acid or base
  3. 4. of conservation of mass during a chemical reaction, the total mass and number of atoms of the reactants equal the total mass and number of atoms of the products
  4. 6. reaction a chemical reaction in which two or more reactants combine to produce a new product
  5. 8. reaction a change in matter that produces new substances with new properties.
  6. 10. displacement reaction a type of chemical reaction in which the metal ions of two different compounds exchange places.
  7. 15. reaction a chemical reaction between an acid and a base that “neutralizes” their acidic and basic properties
  8. 17. reduced in concentration by being mixed with a liquid, such as water
Down
  1. 2. substances that react together in a chemical reaction
  2. 5. reaction a type of reaction in which one compound breaks down into two or more simpler compounds or elements
  3. 6. displacement reaction a type of chemical reaction in which one element takes the place of another element in a compound.
  4. 7. scale a scale from 0 to 14 that describes how acidic or basic a substance is
  5. 9. an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.
  6. 11. a compound that tastes bitter, has a slippery texture, corrodes tissue, and turns red litmus paper blue.
  7. 12. a compound that tastes sour, corrodes metals and tissue, and turns blue litmus paper red
  8. 13. chemical equation represents a chemical reaction using coefficients (numbers in front of the reactants and products) that tell you how much of the reactants are used and how much of the products are made
  9. 14. equation uses words instead of chemical formulas to describe what happens to reactants and products during a chemical reaction
  10. 16. non-toxic base that is used to neutralize stomach acid; relieves the pain of excess stomach acid (acid reflux or heartburn)
