2.  the burning of any substance in O 2 to produce heat CH 4 (g) + 2O 2 (g)  CO 2 (g) + 2H 2 O(g) A + O 2  B

3.  Products: › contain oxygen › hydrocarbons form CO 2 + H 2 O Na(s)+ O 2 (g)  C 3 H 8 (g)+ O 2 (g)  5 3 4 CO 2 (g)+ H 2 O(g) Na 2 O(s) 4 2

4.  the combination of 2 or more substances to form a compound  only one product A + B  AB

5. H 2 (g) + Cl 2 (g)  2 HCl(g)

6.  Products: › ionic - cancel charges › covalent - hard to tell Al(s)+ Cl 2 (g)  AlCl 3 (s) 2 3 2

7.  a compound breaks down into 2 or more simpler substances  only one reactant AB  A + B

8. 2 H 2 O(l)  2 H 2 (g) + O 2 (g)

9.  Products: › binary - break into elements › others - hard to tell KBr(l)  K(s) + Br 2 (l) 2 2

10.  one element replaces another in a compound › metal replaces metal (+) › nonmetal replaces nonmetal (-) A + BC  B + AC

11. Cu(s) + 2AgNO 3 (aq)  Cu(NO 3 ) 2 (aq) + 2Ag(s)

12.  Products: › metal  metal (+) › nonmetal  nonmetal (-) › free element must be more active (check activity series) Fe(s)+ CuSO 4 (aq)  Cu(s)+ FeSO 4 (aq) Br 2 (l)+ NaCl(aq)  N.R.

13.  ions in two compounds “change partners”  cation of one compound combines with anion of the other AB + CD  AD + CB

14. Pb(NO 3 ) 2 (aq) + K 2 CrO 4 (aq)  PbCrO 4 (s) + 2KNO 3 (aq)

15.  Products: › switch negative ions › one product must be insoluble (check solubility table) Pb(NO 3 ) 2 (aq)+ KI(aq)  PbI 2 (s)+ KNO 3 (aq) NaNO 3 (aq)+ KI(aq)  N.R. 2

16. Neutralization Reactions Also known as… Acid: Base: produces H + ions proton (H + ) donor produces OH - ions proton acceptor For a strong acid and base reaction H + (aq) + OH – (aq)  H 2 O(l)

17. Acid: produces H + ions proton (H + ) donor Base: produces OH - ions proton acceptor Also known as… Neutralization Reactions
