WALT: describe chemical reactions and balance equations. WU: Balance the following equation. NaCl F NaF Cl2
CW: Vocabulary
Sulfur + Iron Synthesis Reaction

3. Vocabulary:
Synthesis reaction – elements combine to make a more complex substance. H2 + O2 2 H2O Decomposition reaction – breaks down complex substances into simpler ones. 2 H2O2 2 H2O + O2 Replacement – different compounds trade places.

4. Simplified Rules for balancing equations
Write the equation
Mg + O MgO
Count the atoms
Mg = 1 O2 = MgO = 2
Use Coefficients to balance the Atoms
Mg O MgO
