9)     _____ Fe      +    ____O2 -à   ________       Iron (III) oxide) (Write correct formula, balance)

Explanation / Answer

Solution :-

The balanced equation for the reaction and type of reaction are as follows

Balanced reactions for the each chemical reaction are as follows

1).       2 NaBr + Ca(OH)2 ----- > CaBr2 + 2NaOH            Double displacement reaction

2) 2NH3 + H2SO4 ------ > (NH4)2SO4                      Acid base reaction (combination reaction )

3) 4C5H9O + 27 O2 ------> 20 CO2 + 18 H2O                    Combustion reaction

4) 3Pb + 2H3PO4   ------- > 3H2 + Pb3(PO4)2               redox reaction

5) Li3N + 3NH4NO3 -------- > (NH4)3N + 3LiNO3          double replacement

6) 3HBr + Al(OH)3 ------ > 3H2O + AlBr3              acid base reaction ( double replacement )

7) N2H4 + 2H2O2 ------ > N2 +4 H2O                    redox reaction

8) P4 + 3O2 ---- >2 P2O3                                   synthesis reaction ( combination reaction)

9) 4Fe + 3O2 ----- > 2 Fe2O3                            synthesis reaction ( combination reaction)
