This Year – Period 4 AP Chemistry : Hydrogen Balloon Explosion Comparison:

2 H2 (g)  +  O2 (g)  —>   2 H20  +   Energy 



There are 3 different type of reactions that we identified today and If we include the double replacement reaction that we learned in the solubility unit we know have 4.


*Reactions are not balanced..

                                                  A B               +         C D                    →           A D                 +         C B    

1. Double Replacement –      NaCl (aq)  +   AgNO3 (aq)  →  NaNO3 (aq)   +   AgCl (s)

                                                                                A     +      C D        →         A C         +         D     

2. Single Replacement                            Zn   +   HCl     →   ZnCl2    +    H2

                                                                                A     +        D          →         A D     

3. Synthesis –                                           H2   +   O2     →     H2O    

                                                                                              A  D         →         A       +      D     

4. Decomposition –                                               H20     →     H2   +    O2   


4/8 – Monday’s Homework: – 

1.  Complete tonights worksheet by completing questions 4 – 7 using my video below.

2.  Complete the Form below based on the worksheet below:

 Main focus:

a) To Balance chemical recations.

b) To identify Chemical Reactions and predict products and reactants

c) To introduce stoichiometry Reactions. 

Period  6:

 * review of question 10 of the form from last night –> reactants mass = mass of products

1.  Complete the discussion of the Conservation of Mass presentation.

– We balance because it gives us mole (how many) ratios of the chemicals in the reaction.

– These ratio help us figure out the recipe!!

– Challenger vs Hindenburg

2.  Complete the Synthesis of copper (?) Iodine
