  1. Types of Reactions Combination Reactions and By: Dionna Vereen & Zarmeena Khan

  2. 7.5 Testing Chemical Reactions You can only be 100% certain of the products of a chemical reaction by testing it in the laboratory It’s logical to think since there are millions of chemical compounds, that there must be millions of chemical reactions But carrying out each and every chemical reaction is costly and time consuming So, instead of memorizing, you can learn to recognize patterns of how chemicals behave to predict the products of many chemical reactions True Story

  3. 7.5Typesof Reactions • There are many ways to classify chemical reactions • The 5 general reaction types are: Double Replacement Combination Single Replacement Decomposition & Combustion • Not all reactions fit neatly into one category, sometimes they fit into two • Recognizing a reaction’s particular type is useful in predicting it’s products

  4. True or false The process of learning the products of the many chemical reactions requires a lot of memorizing. TRUUUUUUUUE … FALSE

  5. In a combination reaction, two or more substances react to form a single substance The product of a combination reaction will A L W A Y S be a compound In common combination reactions, the reactants are either two elements or two compounds What is a Combination Reaction? Hmm, good question

  6. Examples of Combination Reactions 2S(s) + 3O (g) 2SO (g) sulfur trioxide 2 3 Fe(s) + S(s) FeS(s) iron(II) sulfide Al(s) + 3At(s) AlAt (s) aluminum astatide 3

  7. More Examples of Combination Reactions Some nonmetal oxides react with water to form an acid When a Group A metal reacts with a nonmetal, the formula for the product is a combination of the metal cationand nonmetal anion Ex. SO (g) + H O(l) H SO (aq) 2 2 3 2 Ex. 2K(s) + Cl (g) 2KCl(s) Metallic oxides react with water to form a base 2 Ex. CaO(s) + H O(l) Ca(OH) (aq) 2 2

  8. What are the Products of these Combination Reactions?

  9. FunFactsBro Combination reactions are the opposite of decomposition reactions. Combination reactions are usually exothermic because when the bond forms between the reactants, heat is released. http://en.wikipedia.org/wiki/Combination_reaction http://library.thinkquest.org/19957/balequa/typeofreactbody.html http://www.brightstorm.com/science/chemistry/chemical-reactions/synthesis-reactions/

  10. YAYHOMEWORK Do all reactions fit neatly into one category? AAAAAAAND… What are the products to these combination reactions? 2Na + Cl ? 2 2Cu + O ? 2
