Name the following compound: ZnCO\u2083<\/strong>
Correct answer: a) Zinc (II) carbonate<\/strong><\/p>\n\n\n\n
The correct name for SrO is:<\/strong>
Correct answer: c) strontium oxide<\/strong><\/p>\n\n\n\n
Which one is a molecular compound?<\/strong>
Correct answer: d) OF\u2082<\/strong><\/p>\n\n\n\n
\n\n\n\nExplanation<\/h3>\n\n\n\n
Zinc carbonate is composed of the zinc ion (Zn\u00b2\u207a) and the carbonate ion (CO\u2083\u00b2\u207b). Since zinc commonly forms only a +2 charge, the Roman numeral II is appropriate, even though it’s often omitted for elements with fixed oxidation states like Zn. So, the correct IUPAC name is zinc (II) carbonate<\/strong>. Option a<\/strong> is correct. Options b and c are incorrect because Zn\u207a (zinc I) does not exist in stable compounds. Option d, zinc carbide, is unrelated.<\/p>\n\n\n\n
Strontium (Sr) is an alkaline earth metal that always forms a +2 charge (Sr\u00b2\u207a). Oxygen typically has a \u22122 charge (O\u00b2\u207b). Combining them in a 1:1 ratio yields SrO. Because Sr has a fixed oxidation state, there’s no need to specify it with Roman numerals. Thus, strontium oxide<\/strong> is the correct name, making option c<\/strong> the right answer. Option a is incorrect because the Roman numeral is unnecessary. Option b refers to a different compound entirely (Sr(OH)\u2082), and option d is not a conventional or correct name.<\/p>\n\n\n\n
Molecular compounds are typically formed between two nonmetals. OF\u2082 (oxygen difluoride) consists of two nonmetals: oxygen and fluorine. These elements form covalent bonds, making it a molecular compound. In contrast:<\/p>\n\n\n\n\n
