KEY TERMS ALL

Explain the significance of a chemical formula. Determine the formula of an ionic compound formed between two given ions. Name an ionic compound given its formula. Using prefixes, name a binary molecular compound from its formula. Write the formula of a binary and ternary molecular compound given their name. List the rules for assigning oxidation numbers. Give the oxidation number for each element in the formula of a chemical compound. Name binary molecular compounds using oxidation numbers and the Stock system.

Calculate the formula mass or molar mass of any given compound. Use molar mass to convert between mass in grams and amount in moles of a chemical compound. Calculate the number of molecules, formula units, or ions in a given molar amount of a chemical compound. Use conversion factors to convert between grams, moles, molecules, formula units, or ions Calculate the percentage composition of a given chemical compound. *REMEMBER to SHOW your work –use STEPS shown on SAMPLE PROBLEMS that you COPIED on CW packet from PPT (board)
