Question

10 unbalenced and balanced chemichal reactions

Answer 1

1.  __ AgI + __ Na2S → __ Ag2S + __ NaI                   
                  2 AgI + 1 Na2S → 1 Ag2S + 2 NaI

2. __ Ba3N2 + __ H2O → __ Ba(OH)2 + __ NH3
                      1 Ba3N2 + 6 H2O → 3 Ba(OH)2 + 2 NH3


3.__ CaCl2 + __ Na3PO4 → __ Ca3(PO4)2 + __ NaCl
                       3 CaCl2 + 2 Na3PO4 → 1 Ca3(PO4)2 + 6 NaCl


4. __ FeS + __ O2 → __ Fe2O3 + __ SO2
                    4 FeS + 7 O2 → 2 Fe2O3 + 4 SO2


5. __ PCl5 + __ H2O → __ H3PO4 + __ HCl
                   1 PCl5 + 4 H2O → 1 H3PO4 + 5 HCl


6. __ As + __ NaOH → __ Na3AsO3 + __ H2
                   2 As + 6 NaOH → 2 Na3AsO3 + 3 H2


7. __ Hg(OH)2 + __ H3PO4 → __ Hg3(PO4)2 + __ H2O
                3 Hg(OH)2 + 2 H3PO4 → 1 Hg3(PO4)2 + 6 H2O


8.__ HClO4 + __ P4O10 → __ H3PO4 + __ Cl2O7          
               12 HClO4 + 1 P4O10 → 4 H3PO4 + 6 Cl2O7


9.__ CO + __ H2 → __ C8H18 + __ H2O
                  8 CO + 17 H2 → 1 C8H18 + 8 H2O


10.__ KClO3 + __ P4 → __ P4O10 + __ KCl
               10 KClO3 + 3 P4 → 3 P4O10 + 10 KCl
