Predicting Single Replacement Reactions

Step by Step rules

1. Check table J and see if the single element is above the element it will replace (metals replace metals and nonmetals replace nonmetals).

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 origonal 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-Highlight to reveal answers.
	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
