  1. 2 AlCl3 (s)+ 3H2O -->
  2. Al2O3 (s)+ 2 NaOH (aq) + 3 H2O -->
  3. Solubility of hydrogen halides
  4. Alkali metals can react with peroxide. Write the formula when sodium reacts with it. What alkali metal will not react with lithium?
  5. Al2O3 + H2O -->
  1. a NO REACTION
  2. b NaAl(OH)4 (aq)
  3. c Very soluble. HF is the weakest since it sometimes does not dissociate in water.
  4. d Al2O3 (s) + 6HCl (aq)
  5. e 2Na(s)+O2(g)-->Na2O2(s)
    Lithium will not react with peroxide.

  2. SiO2 (s)+ 2 NaOH (aq) -->AT 350 DEGREES CELSIUS. Na2SiO3 (aq) + H2O

          

  3. Halogens react with metals to form what?Metal halides (Ionic bonding).

          

  4. MgO + H2O -->NaOH (Basic and soluble)

          

  5. Alkali metals in water react exothermically to form metal hydroxides. Write the general equation, where M is any alkali metals.2M(s)+2H2O(l)-->2M-(aq)+2OH-(aq)+H2(g)
