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 . 1. Lithium hydroxide + carbonic acid  2. Silver nitrite + Beryllium chlorate  3. Lead(II) oxide + Strontium carbonate  4. Magnesium hydroxide + nitrous acid  Upper left: Thermite reaction, Fe2O3 + Al => 2Fe +2Al2O3 + HEAT!!! http://en.wikipedia.org/wiki/Thermite Upper right: potassium in water, K + H2O => KOH + H2 + HEAT Bottom right: potassium chlorate and sugar, C12H22O11 + 8KClO3 => 12CO2 + 11H2O + 8KCl + HEAT!!! http://lecturedemos.chem.umass.edu/chemReactions5_5.html Bottom left: magnesium reacting with oxygen, Mg + O2 => MgO

After today you will be able to… Predict the products in formulas for a combustion reaction Balance combustion reactions heat Pt

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

___ 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.

___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!
