CHEM 120 FINAL EXAM QUESTIONS WITH COMPLETE SOLUTION

ionic compounds correct answer: -deals with charged particles -oppositely charged particles are attracted to each other -look for presence of metals and polyatomic ions molecular compounds correct answer: -share electrons -nonmetals -no polyatomic ions unless its an acid Type I metals correct answer: -ionic compounds -group 1A,2A,3A -one type of charge state -Name of metal +ion -if metal+nonmetal: name of metal+base name of nonmetal +ide -if metal+polyatomic ion: name of metal+name of polyatomic ion Type II metals correct answer: -ionic compounds -charge states vary -Name of metal+it's charge as a roman numeral+ion -if metal+nonmetal: name of metal+its charge as a roman numeral+base name of nonmetal+ide -if metal+polyatomic ion: name of metal+its charge as a roman numeral+name of polyatomic ion Molecular compounds: nonmetal+nonmetal correct answer: -prefix+name of 1st nonmetal+prefix+name of second nonmetal -no mono for first nonmetals Acids correct answer: -are molecular compounds but behave like ionic compounds when put in water -dissolved in water(aqueous) -binary or oxy acids Binary acids correct answer: -hydro+base name of second nonmetal+ic+acid -hydro means no oxygen present Oxy acids correct answer: -contains oxygen as a part of a polyatomic ion -ate becomes ic -ite becomes ous -ex: HNO₃→nitric acid ACID EXCEPTIONS correct answer: H₂SO₄→sulfu
