Question

Finish these reactions with correct products & formulas.

1a. Si + H2----------> (composition)

b. Zn + AlCl3----------> (check activity series)

c. Ba + H2O (liquid)----------> (check activity series)

d. NaOH(aq) + ZnCl2(aq)---------->

e. Ca(ClO3)2----------> (check decomposition rules)

f. KOH (aq) + H2SO4(aq)---------->( is this a chemical reaction and why?)

g. NH4Cl(aq)+ Ca(C2H3O2)2(aq)----------> ( is this a chemical reaction and why?)

h.zinc chloride + Aluminum Phosphate  ------------------> zinc phosphate +Aluminum Chloride (double replace)

i. Finish reaction, then balance, and determine the net ionic equation for this precipitate reaction:

AgClO3 + CaCl2 -------------------> ______ + _________

net ionic equation:

Answer 1

a. Si + 2H2----------> SiH4

b. 3Zn + 2AlCl3----------> 2Al + 3ZnCl2

c. Ba + 2H2O ----------> H2 + Ba(OH)2

d. 2NaOH(aq) + ZnCl2(aq)----------> Zn(OH)2 (s)+ 2NaCl (aq)

e. Ca(ClO3)2---------->CaCl2 + 3O2

f. 2KOH (aq) + H2SO4(aq) ----------> K2SO4 (aq) +2H2O (l)

g. 2NH4Cl(aq)+ Ca(C2H3O2)2(aq) ----------> CaCl2 + 2NH4C2H3O2

h. 3ZnCl2 + 2Al PO4 ------------------> Zn3 (PO4)2 +2AlCl3

i. AgClO3 (aq) + CaCl2 (aq)-------------------> AgCl (s) + Ca(ClO3)2 (aq)

Net ionic equation

Ag⁺ + Cl^- gives AgCl (s)
