1. Types of Chemical Reactions

2. Synthesis Reactions Reactants  Products 2Li (s) + F 2(g)  2LiF (s)

3. NaCl Crystal

4. Synthesis Reaction Reactants  Products 2Li (s) + F 2(g)  2LiF (s) Note the 2 in front of the Li on the reactant side and the 2 in front of the LiF on the product side are called a coefficients.

5. Synthesis Reaction 2Li (s) + Br 2(l)  2LiBr (s) Lithium Bromide

6. Synthesis Reaction 2Li (s) + Cl 2(g)  2 LiCl (s) Lithium Chloride Sodium plus Iodine 

7. Synthesis Reactions Na (s) + I 2(s) 

8. Synthesis Reactions 2Al (s) + 3S (s)  Al 2 S 3(s)

9. Synthesis 2Mg (s) + O 2(g)  2MgO (s) Magnesium Oxide

10. Synthesis Reactions Try doing the reactions found on the following slides. See if you can:  determine the phase (solid, liquid or gas), of each reactant and product.  Determine the product of the reaction.  Balance the reaction.
