Balancing and Types of Chemical Reactions Text pp Notes: I.N. pp

Chemical Reactions – 1. What types of bonds occur when two elements react?

Chemical Reactions - Types When two elements react, a reaction occurs. If a metal and a nonmetal react, the product is ionic with a formula determined by the charges on the ions the elements form.

Chemical Reactions - Types If two nonmetals react, the product is a molecule with covalent bonds

Examples:Examples: K + S 8  K 2 S (ionic) Ca + O 2  CaO (ionic) Al + I 2  AlI 3 (ionic) H 2 + O 2  H 2 O (covalent) I 2 + Cl 2  ICl, ICl 3, or ICl 5 (covalent)

Chemical Reactions - Types 2. What are the three types of chemical reactions?

Chemical Reactions - Types The three types of reactions are: Synthesis Synthesis Decomposition Decomposition Replacement Replacement

Chemical Reactions - Types Synthesis:Synthesis: A + B  AB A + B  AB

Chemical Reactions - Types Decomposition:Decomposition: AB  A + B AB  A + B

Chemical Reactions - Types Replacement: (single atom)Replacement: (single atom) AB + C  AC + B AB + C  AC + B

Chemical Reactions - Types Replacement: (single atom)Replacement: (single atom) AB + C  AC + B AB + C  AC + B or AB + C  CB + A

Chemical Reactions - Types Replacement: (two atoms)Replacement: (two atoms) AB + CD  AD + CB AB + CD  AD + CB (this is called a double- replacement)

Chemical Reactions - Amounts  Don’t Forget: When balancing chemical reactions, the When balancing chemical reactions, the MASS of the PRODUCTS must equal the MASS of the REACTANTS MASS of the PRODUCTS must equal the MASS of the REACTANTS This means that there must be the same number of each type of atom on both sides of the arrow. This means that there must be the same number of each type of atom on both sides of the arrow.

Chemical Reactions - For each of the following equations give the following information: 1.What are the reactants/products? 2.Show the balanced equation. 3.Identify the type of reaction: synthesis, decomposition or replacement?

Remember: When they broke open molecules, they found they were only stuffed with atoms. But when they broke open atoms, they found them stuffed with explosions !

Chemical Reactions - Are we having fun yet?

A chemist walks into a pharmacy and asks the pharmacist, "Do you have any acetylsalicylic acid?" "You mean aspirin?" asked the pharmacist. "That's it, I can never remember that word."

Little Johnny took a drink, Now he shall drink no more. For what he thought was H 2 O, Was H 2 SO 4. Be careful what you drink… sometimes a harmless-looking clear solution can be deadly! Sulfuric acid (H 2 SO 4 ) is a highly corrosive, poisonous acid.
