chemistry plz help!!!

are the following true for the element gallium? if they are false make them true.

oxide more basic than Al203
oxide less basic than Mg(OH)2
hydroxide soluble in acid
hydroxide soluble in base
sulfide precipitates with H2S
sulfide not soluble in (NH4)2S
will form EaCl3, Ea2S3, and alum
EaCl3, Ea2S3, and alum soluble
will be discovered by spectrum

are the following true for the element scandium? if they are false make them true.
EbCl3 less volatile than AlCl3
will form Eb2O3
density of Eb2O3 = 3.5 g/cm3
ocide more basic than Al2O3
oxide less basic than Y2O3
oxide less basic than Mg(OH)2

  1. You can get much of this information from the
    1. periodic table (www.webelements.com)or
    2. by going to www.google.com and typing in the name of the compound or
    3. reviewing the periodicity of the periodic table in your text/workbook.
    For example, EaCl3 would be translated to GaCl3 (it's actually present as Ga2Cl6), Ea2S3 would be translated to Ga2S3. etc.


    oxide more basic than Al203
    oxide less basic than Mg(OH)2
    hydroxide soluble in acid yes
    hydroxide soluble in base yes
    sulfide precipitates with H2S yes
    sulfide not soluble in (NH4)2S yes
    will form EaCl3, Ea2S3, and alum
    EaCl3, Ea2S3, and alum soluble
    will be discovered by spectrum yes

    I typed in density scandium oxide and found a density (first article) of 3.86 g/cc and not the 3.5 listed).
    are the following true for the element scandium? if they are false make them true.
    EbCl3 less volatile than AlCl3 You would want this to read ScCl3 and you can look up the boiling point (the volatility) of ScCl3 and AlCl3 on google.)
    will form Eb2O3 Sc2O3
    density of Eb2O3 = 3.5 g/cm3 3.86 g/cc
    ocide more basic than Al2O3
    oxide less basic than Y2O3
    oxide less basic than Mg(OH)2
    I hope this gets you started.
