Apologia Chemistry Module 5, 3rd Edition Quizes 2024.How many oxygen atoms are in an Al2 (CO3)3 molecule? A. 3 B. 6 C. 9 D. 12 - ANSWER C. 9 Polyatomic ions are often said to be a cross between covalent compounds and ionic compounds. Why can they be characterized in such a way? - ANSWER Because Polyatomic ions have groups of atoms that share electrons like covalent compounds but they have extra electrons that are similar to ionic compounds. In VESPR theory, which repels other electr...

Chemistry Final Exam (Answered) Oxidation Rules Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) -Mg=0,H2=0, C=0 Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion -Mg^2+=+2, Na^+=+1, O^2-=-2 Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. Rule 4: The oxidation numb...
