Translate,
predict the products, balance:
Lithium metal reacts with cobalt (II) chloride
solution. What are the products?
HW: Finish Double Replacement

Slide3Objectives
IWBAT
Classify reactions by type and predict the products of simple:
Synthesis
Decomposition
Single Replacement
Double Replacement
Combustion
reactions
NOTE: Let Ms. Bloedorn know if you are interested in going to the Howard County STEM Fair (or other STEM Fairs)!
Slide4HW/SR Review
Let’s put some equations on the boards!!!
Single Replacement WS

Slide5Double Replacement ReactionsAB + CD
AD + CB
Compound + Compound
New Compound + New Compound
These are always in
aqueous
solutions, and one product is either a solid precipitate, a gas, or a liquid (usually water).
To predict, swap ion pairs and re-cross charges.
Check the
solubility chart
to see if anything precipitates
