b. 2 Fe + 3 Br2 rtarrow.gif (850 bytes) 2 FeBr3

c. 2 CaO rtarrow.gif (850 bytes) 2 Ca + O2

d. K2SO4 + CaCl2 rtarrow.gif (850 bytes) 2 KCl + CaSO4

e. Al(NO3)3 + 3 NaOH rtarrow.gif (850 bytes) Al(OH)3 + 3 NaNO3

f. magnesium + zinc bromide rtarrow.gif (850 bytes) zinc + magnesium bromide
( Mg + ZnBr2 rtarrow.gif (850 bytes) Zn + MgBr2 )

g. sodium chloride rtarrow.gif (850 bytes) sodium + chlorine
( 2 NaCl rtarrow.gif (850 bytes) 2 Na + Cl2 )

For additional practice try categorizing the reactions represented by the equations in example 3 in your workbook. If you have trouble with any of those, check with your instructor.
