Objective:
◦ Today I will be able to:
 Determine the purpose of the activity series of metals by completing an
online lab


 Predict the products of single replacement reactions
 Use the activity series of metals and the periodic table to
determine if a single replacement reaction will occur
Evaluation/Assessment:
◦ Informal assessment: Listening to student interactions as they
complete the lab and practice
◦ Formal assessment: Analyzing student responses to the lab and
practice problems
Common Core Connection
◦ Use technology and digital media strategically and capably
◦ Build Strong Content Knowledge
◦ Make sense of problem and persevere in solving them

Predicting Products
A free element reacts with a compound to
form a new compound and to release one
of the elements of the original compound
General Equation: AB + C  AC + B
Examples



◦
◦
2 HCl + Mg  MgCl2 + H2
2 KI + Cl2  2 KCl + I2
Metallic Free
•Free element is a metal
•Most common
•Example
•Mg + 2HCl  MgCl2 + H2
Non – Metallic Free
•Free element is a non-metal
•Example
•KI + Cl2  KCl + I2


Use the activity
series of metals
Anything higher on
the list as a free
element will replace
anything lower on
the list from a
compound






Na + PbCl2 
2 Na + PbCl2  2 NaCl + Pb
This reaction occurs because sodium is
higher on the activity series than lead
Al + NaCl 
Al + NaCl  No Reaction
This reaction does not occur because
aluminum is NOT higher on the activity series
than sodium



Use the periodic
table
Any free element
higher in a family
on the Periodic
Table can replace
any lower element
from a compound.
Why does this
work?






Cl2 + NaI 
Cl2 + 2 NaI  2 NaCl + I2
This reaction occurs because chlorine is
higher in its family than iodine
S + H2O 
S + H2O  No Reaction
This reaction does not occur because sulfur is
lower in its family than oxygen
Complete the practice at your desk. We will
continue to work on the practice problems in
class tomorrow.

Explain why the reaction between has no
reaction
◦ NaF + Br2  No Reaction
