Chemical Reactions – Nomenclature ISCI 2002

1. Binary Compounds – Naming –Ending: Replace with –ide – NaCl (sodium chloride) 2. Writing –Oxidation numbers –Criss-cross method

Name the following: –MgCl 2 –K 2 O Write the following compounds –Sodium fluoride –Aluminum chloride

1. Naming –Polyatomic ions –NaOH (sodium hydroxide) 2. Writing –Criss-Cross and oxidation numbers

Name: –CaO –LiCl 2 Write: –Magnesium carbonate –Sodium hydroxide

Use Prefixes Name –CO 2 –N 2 O 3 Write: –Diphosphorus pentaoxide

1. Determine the initial number of individual atoms on both –List numbers 2. Balance by inspection

3. Single Displacement –A + BC  AC + B 4. Double Displacement –AB + CD  AD + CB

Rules –1. Use oxidation numbers to write individual compounds –2. For products, you must write ‘new’ compounds using oxidation numbers –3. Write states of matter if applicable –4. Identify the type of chemical reaction

Sodium metal + chlorine gas  solid sodium chloride. Copper metal + aqueous silver nitrate ----  silver metal + copper (I) nitrate

1. You must know the classification type. 2. Write compounds individually –Ignore how the atoms were written on the reactant side

Magnesium metal is heated and exposed to oxygen gas Aqueous calcium chloride decomposes A solution of Lead (II) nitrate is added to a solution of potassium iodide.
