Single Displacement Reaction and Double Displacement reactions. Balance each for

Question

Single Displacement Reaction and Double Displacement reactions. Balance each formula, if the formulas are given, predict the products and write out the work equation. If the words are given then write out the formulas and balance the equation. Write which type of equation it is for each problem. Ca + HBr right arrow H_2O + K right arrow Cl_2 + CaBr right arrow Cu(OH)_2 + CaCI_2 right arrow Zn(OH)_2 + H_2SO_4right arrow Barium Sulfate + Oxygen right arrow Fluorine + Nickel II Chloride right arrow Sodium Chloride + Copper(I)Sulfate right arrow

Explanation / Answer

1]

Ca + 2 HBr = CaBr2 + H2 [ single displacement]

2]

2H2O + 2K = 2KOH + H2

single replacement

3]

Cl2 + CaBr2 = CaCl2 + 2Br

single displacement

4]

Cu(OH)2 + CaCl2.= CuCl2 + Ca(OH)2

Double replacement

5]

H2SO4 + Zn(OH)2 = ZnSO4 + 2H2O

Double displacement

6]

Dont know

7]

F2 + NiCl2 ----> NiF2 + Cl2

SIngle displacement reaction

8]

NaCl + Cu2SO4 ------> Na2SO4 + CuCl

Double displacement
