1 Predicting Reaction Products

2 Once you classify a chemical reaction, write the products and balance the reaction.

3 Review Diatomic Molecules! Elements that exist only as compounds in the natural world: Iodine I 2 Hydrogen H 2 Nitrogen N 2 Bromine Br 2 Oxygen O 2 Chlorine Cl 2 Fluorine F 2 I HAVE NO BrIGHT OR ClEVER FRIENDS

4 Combustion (Easiest) 1. Reactants are always a hydrocarbon and oxygen. 2. Products are always CO 2 and H 2 O. C 4 H 10 + O 2 CO 2 + H 2 O

5 Combustion: Let s Practice! 1) CH 4 + O 2 CO 2 + H 2 O 2) C 10 H 22 + O 2 3) CH 3 OH + O 2 4) C 12 H 22 O 12 + O 2 CO 2 + H 2 O CO 2 + H 2 O CO 2 + H 2 O

6 Synthesis Two or more combine into one!

7 Synthesis Let s Practice! 1) Ba + O 2 2) Li + Br 2 3) Ni(II) + F 2 BaO LiBr NiF 2 4) Cu(II) + CO 3 2-5) Cu(II) + O 2 CuCO 3 CuO

8 Decomposition One compound splits into two or more pieces.

9 Decomposition Let s Practice! 1) NaCl 2) RaCl 2 Na + Cl 2 Ra + Cl 2

10 Single Displacement Reactants and products consist of an element and a compound. Replacement depends upon reactivities of the two metals. The activity series lists metals in order of decreasing reactivity. So you have to be above the element in order to kick it out! If it is not above then NO REACTION!

13 Double Displacement Positive ions switch partners. Most reactions include two aqueous solutions being mixed together so the ions can interact. If the ions connect to form something new you will make either a solid or liquid (sometimes gas) called a precipitate. If none of the above are made you did nothing!

14 Double Displacement In double- displacement reactions, water as a product, is often written as HOH so you can more easily see the exchange of atoms/compounds. HCl (aq) + NaOH (aq) -> HOH (l) + NaCl (aq)

15 Precipitate Formed when two soluble salts react in solution to form one or more insoluble products.

16 Double Displacement Let s Practice! 1) BaCl 2 + Na 2 CO 3 BaCO 3 + NaCl 2) Al 2 (SO 4 ) 3 + H 3 PO 4 AlPO 4 + H 2 SO 4 3) HNO 3 + NaCl 4) NH 4 Cl + Ba(OH) 2 HCl + NaNO 3 NH 4 OH + BaCl 2 5) AgClO 3 + Ni(NO 3 ) 2 AgNO 3 + Ni(Cl) 3 ) 2

17 Double Displacement Let s Practice! 6) PbCl 4 + H 3 PO 4 Pb 3 (PO 4 ) 4 + HCl 7) K 2 SO 4 + MgF 2 8) MgCO 3 + CaCl 2 KF + MgSO 4 MgCl 2 + CaCO 3 9)AlCl 3 + BaSO 4 10)Zn(OH) 2 + H 2 SO 4 Al 2 (SO 4 ) 3 + BaCl 2 ZnSO 4 + H 2 O
