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: – MgCl2– K2O

• Write the following compounds – Sodium fluoride – Aluminum chloride

• 1. Naming– Polyatomic ions – NaOH (sodium hydroxide)

• 2. Writing– Criss-Cross and oxidation numbers

• Name: – CaO

– LiCl2

• Write:– Magnesium carbonate – Sodium hydroxide

• Use Prefixes

• Name– CO2

– N2O3

• 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.
