1. Check table J and see if the single element is above the element
it will replace based on activity (metals replace metals and
nonmetals replace nonmetals). you can see the reaction rates of
different metals below.
2. If Yes, Write the formulas
3. Write the names
of products (switch names)
4. Write the correct
formulas of products, based on charge not original formula.
5. Balance
If the element that is to replace the other in the compound is
higher on the chart, the reaction will occur. If it is below,
there will be no reaction.
Examples-
Zn + CuCl2
--->
ZnCl2 + Cu
Cl2 + 2NaBr
--->
2NaCl + Br2
Mg + 2HCl
--->
MgCl2 + H2
Cu + AgNO3
--->
Ag + Cu(NO3)2
Cu + AlCl3
--->
no reaction
Fe + Cu(NO3)2
--->
Fe(NO3)2 + Cu
Br2 + 2KI
--->
2KBr + I2
2Al +
3Pb(NO3)2
--->
2Pb + 2Al(NO3)3
Br2 + CaI2
--->
I2 + CaBr2
I2 + NaCl
--->
no reaction
Copper metal in a solution of silver nitrate produces Silver
metal and blue copper nitrate solution.
