  8. Oxides Synthesis review: M + O2 (g) M oxide M oxide + H2O(l)  M hydroxide Metal oxides are called basic oxides because they form bases when mixed with water. Ionic compound, solid! Na(s) + O2 (l) BASE

  9. Oxides Synthesis review: M + O2 (g) M oxide M oxide + H2O(l)  M hydroxide Metal oxides are called basic oxides because they form bases when mixed with water. Ionic compound, solid! Na(s) + O2 (l) Na2O (s) BASE

  10. Oxides Synthesis review: M + O2 (g) M oxide M oxide + H2O(l)  M hydroxide Metal oxides are called basic oxides because they form bases when mixed with water. Ionic compound, solid! 4 Na(s) + O2 (l) 2 Na2O (s) Na2O (s) + H2O(l) BASE

  11. Oxides Synthesis review: M + O2 (g) M oxide M oxide + H2O(l)  M hydroxide Metal oxides are called basic oxides because they form bases when mixed with water. Ionic compound, solid! 4 Na(s) + O2 (l) 2 Na2O (s) Na2O (s) + H2O(l) NaOH (aq) BASE

  15. Oxides Synthesis review: NM + O2 (g) NM oxide NM oxide + H2O(l)  acid Non-metal oxides are called acidic oxides because they form acids when mixed with water. Covalent molecule, gas! SO3 (g) + H2O (l) ACID

  16. Oxides Synthesis review: NM + O2 (g) NM oxide NM oxide + H2O(l)  acid Non-metal oxides are called acidic oxides because they form acids when mixed with water. Covalent molecule, gas! SO3 (g) + H2O (l) H2SO4 (aq) ACID Pollutant

  17. Neutralization AB + CD  AD + CB Product of DD reactions: neutralized solution (pH closer to 7) What evidence tells us there was a reaction?

  18. Stomach acid What’s in our stomach? HCl(aq) Add an antacid when acid reflux

  19. Stomach acid What’s in our stomach? HCl(aq) + Al(OH)3(s) Add an antacid when acid reflux

  20. Stomach acid What’s in our stomach? HCl(aq) + Al(OH)3(s) AlCl3(aq) + H2O(l) Add an antacid when acid reflux
