    Explanation<\/h3>\n\n\n\n

    1. Fe\u2083(PO\u2083)\u2082 \u2013 Iron(II) phosphite:<\/strong>
    This is an ionic compound composed of iron and the phosphite ion (PO\u2083\u00b3\u207b). Iron can have multiple oxidation states, so we determine which is present:
    Each PO\u2083\u00b3\u207b has a -3 charge, and there are two of them for a total of -6. To balance this, the total charge from the iron must be +6. With three Fe atoms, each must be +2. Thus, we name it Iron(II) phosphite<\/strong>, indicating Fe\u00b2\u207a.<\/p>\n\n\n\n

    2. N\u2083S\u2087 \u2013 Trinitrogen heptasulfide:<\/strong>
    This is a covalent compound made of nonmetals, so we use prefixes to indicate the number of atoms. \u201cTri-\u201d for three nitrogen atoms and \u201chepta-\u201d for seven sulfur atoms gives us Trinitrogen heptasulfide<\/strong>.<\/p>\n\n\n\n

    3. NH\u2083 \u2013 Ammonia:<\/strong>
    NH\u2083 is a well-known covalent compound with a common name: ammonia<\/strong>. Though it could be named “nitrogen trihydride,” the common name is more widely accepted and used in practice.<\/p>\n\n\n\n

    4. H\u2082SeO\u2084 (aq) \u2013 Selenic acid:<\/strong>
    This is an oxoacid (acid containing oxygen). The anion here is selenate (SeO\u2084\u00b2\u207b). According to naming rules, “-ate” anions become “-ic acid” when naming acids. Therefore, H\u2082SeO\u2084 is selenic acid<\/strong>.<\/p>\n\n\n\n

    5. MnSO\u2084 \u00b7 6H\u2082O \u2013 Manganese(II) sulfate hexahydrate:<\/strong>
    This is a hydrated ionic compound. Mn forms +2 ions here (sulfate is SO\u2084\u00b2\u207b), so we name it Manganese(II) sulfate<\/strong>. The \u201c\u00b7 6H\u2082O\u201d indicates six water molecules per formula unit, which we denote as hexahydrate<\/strong>. Hence, the full name is Manganese(II) sulfate hexahydrate<\/strong>.<\/p>\n\n\n\n

    These naming conventions are based on IUPAC (International Union of Pure and Applied Chemistry) standards for chemical nomenclature.<\/p>\n\n\n\n
