Upper left: Thermite reaction, Fe2O3 + Al => 2Fe +2Al2O3 + HEAT!!!
Upper right: potassium in water, K + H2O => KOH + H2 + HEAT
Bottom right: potassium chlorate and sugar, C12H22O11 + 8KClO3 => 12CO2 + 11H2O + 8KCl + HEAT!!!
Bottom left: magnesium reacting with oxygen, Mg + O2 => MgO

2. After today you will be able to…
Identify a single replacement reaction
Predict the products in words for single replacement reactions
heat Pt

3. Element + Compound  Element +Compound
Predicting Products
Single Replacement: An element and compound react to form a different element and compound
Common form:
Element + Compound  Element +Compound
A + BC  AC + B
heat Pt

4. Predicting Products These reactions do not always occur.
You must use the “activity series” sheet
“Like will replace like” – metals always replace metals, etc.
