Answer #1

Combination Reaction :- 2 reactants combine to give a single product.

Decomposition :- Single reactant is decomposed into 2 or more products.

Combustion :- Burning of an organic compound in presence of oxygen which releases energy. Combustion products are CO2 and H2O.

Single Displacement :- One element replace another element from a compound.

Double displacement :- Two compounds react, cation and anion replaces their position.

Decomposition ______1.    2Al2O3  →  4Al      +    3O2   

Single Displacement______2.   Br2     +   BaI2    →    BaBr2     +     I2

Combustion_________3.    2C2H2  +  5O2      →     4CO2      +    2H2O  + energy

Double displacement__________4.   BaCl2   +  K2CO3 →    BaCO3    + 2KCl

Combination Reaction__________5.  Pb        +    O2      →     PbO2

Combination Reaction________6. H2          +    Br2    →     2HBr

Double displacement________7. AgNO3   +   NaCl  →     AgCl     +   NaNO3

Decomposition________8. 2H2O2    →    2H2O      +      O2

Single Displacement________9.  Zn       +    CuCl2   →    Cu         +    ZnCl2

Combustion__________10. C5H8   +   7O2      →   5CO2      +   4H2O    +  energy

Double displacement_______11. CuO   +    2HCl    →   CuCl2     +    H2O

Combination Reaction________12. 2Al     +    3Br2     →   2AlBr3    

Combustion________13. 2C2H2  +   5O2     →   4CO2      +  2H2O   +  energy

Single Displacement_________14. Fe2O3  +   3C        →   2Fe         +  3CO

Decomposition________15.  C6H12O6  →    2C2H6O     +     2CO2
