Single Replacement One element replaces a similar element in a compound A + BX AX + B A replaces B if A and B are similar Metals can replace less reactive metals Al + Fe(NO 3 ) Al(NO 3 ) + Fe
Metals can replace H Mg + HCl MgCl 2 + H 2 Na + H 2 O NaOH + H 2
Halogens can replace other halogens Br 2 + KCl KBr + Cl 2
Single Replacement Reactions 1) Al + Cu(NO 3 ) 2 2) NaCl + F 2 3) K + H 2 O 4) Na + Mg(OH) 2 5) Ni + FeSO 4
Double Replacement Ions of two compounds exchange places AX + BY AY + BX Double Replacement reactions are often evidenced be the formation of a precipitate or the production of a gas
Practice 1. HCl (aq) + AgNO 3(aq) 2. CaCl 2(aq) + Na 3 PO 4(aq) 3. Pb(NO 3 ) 2(aq) + BaCl 2(aq) 4. FeCl 3(aq) + NaOH (aq) 5. H 2 SO 4(aq) + NaOH (aq) 6. KOH (aq) + CuSO 4(aq)
Mixed Practice State the type, predict the products, and balance the following reactions: 1. BaCl 2 + H 2 SO 4 2. C 6 H 12 + O 2 3. Zn + CuSO 4 4. Cs + Br 2 5. FeCO 3
Types of Reactions You need to be able to identify each type.
Types of Reactions and Predicting Products. Types of Reactions There are four main types of chemical reactions: Synthesis Synthesis Decomposition Decomposition.
Ch 8 - Chemical Reactions. Types of Reactions There are five types of chemical reactions we will talk about: Combination (or synthesis) reactions.
Types of Chemical Reactions. Steps to Writing Reactions Some steps for doing reactions 1.Identify the type of reaction 2.Predict the product(s) using.
Types of Chemical Reactions. Watch These Reactions!

Types of Chemical Reactions Writing Chemical Reactions.
How do chemists know what to mix together to make the products they want??? Substances react with one another in similar ways depending on their chemical.
Classifying Chemical Reactions
Mass is never created or destroyed-ALL must be conserved and accounted for during a chemical reaction The same number of atoms of reactant elements.
Chemistry Ch 8 - Chemical Reactions Reactions & Equations When you take substances and rearrange their atoms to form new substances you have created.
