1. DO NOW: Directions: Predict the products in words for the following
DO NOW: Directions: Predict the products in words for the following double replacement reactions Lithium hydroxide + carbonic acid  Silver nitrite + Beryllium chlorate  Lead(II) oxide + Strontium carbonate  Magnesium hydroxide + nitrous acid 
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…
Predict the products in formulas for a combustion reaction
Balance combustion reactions
heat Pt

3. If your reactant contains:
Predicting Products
Combustion: A reaction with oxygen (O2)
If your reactant contains:
The product will be: C
CO2 H
H2O S
SO2 N N2
heat Pt

4. ___ CH4 + ___O2  ___CO2 + ___H2O Tip: Balance the O2 last.
Examples: Predict the products and balance.
___ CH4 + ___O2  2
___CO2
+ ___H2O 2 1 C 1 4 H 2 4 4 2 O 3 4
Tip: Balance the O2 last.

5. ___H3N + ___O2  ___H2O + ___N2
Examples: Predict the products and balance.
___H3N + ___O2  4 3 6 2 2
1.5
___H2O 3
+ ___N2 12 6 3 H 2 6 12 4 2 1 N 2 4 6 2 O 1 3 6
Tip: Put the ideal decimal coefficient, then double all coefficients to balance!
