Formula and Name of the Compound Formed Between Mg and P:<\/strong> Answer:<\/strong> Mg\u2083P\u2082; Magnesium Phosphide<\/strong><\/li>\n\n\n\n
Covalent Compound from the Given Choices:<\/strong> Answer:<\/strong> H\u2082S<\/strong><\/li>\n\n\n\n
1. Naming the Compound Mg\u2083P\u2082:<\/strong><\/p>\n\n\n\n
The compound formed between magnesium (Mg) and phosphorus (P) is Mg\u2083P\u2082<\/strong>, and its correct name is Magnesium Phosphide<\/strong>. Magnesium is a metal that forms a +2 cation (Mg\u00b2\u207a), and phosphorus is a nonmetal that forms a -3 anion (P\u00b3\u207b). To balance the charges, we need three Mg\u00b2\u207a ions for every two P\u00b3\u207b ions, resulting in the neutral formula Mg\u2083P\u2082. The name does not require Roman numerals or prefixes because it is an ionic compound<\/strong> with a metal of fixed charge.<\/p>\n\n\n\n
2. Identifying the Covalent Compound:<\/strong><\/p>\n\n\n\n
Out of the compounds given: LiC, K\u2082S, H\u2082S, and Rb\u2082S, only H\u2082S (Hydrogen Sulfide)<\/strong> is a covalent compound<\/strong>. Covalent compounds typically form between nonmetals. Hydrogen and sulfur are both nonmetals, so they share electrons to form covalent bonds. The others (LiC, K\u2082S, Rb\u2082S) all contain a metal and a nonmetal, forming ionic compounds<\/strong> through electron transfer rather than sharing.<\/p>\n\n\n\n
3. Balancing the Reaction:<\/strong><\/p>\n\n\n\n
The unbalanced reaction is: NaNO\u2082 + INa + O\u2082 \u2192 NaIO\u2082 + N\u2082<\/p>\n\n\n\n
To balance the atoms:<\/p>\n\n\n\n
\n
Start with the nitrogen atoms. Since NaNO\u2082 has one nitrogen, and N\u2082 is diatomic, we need two NaNO\u2082 molecules to produce one N\u2082 molecule.<\/li>\n\n\n\n
Match the number of iodine and sodium atoms. We see two INa on the left and two NaIO\u2082 on the right.<\/li>\n\n\n\n
Add up the oxygens and adjust O\u2082 as needed.<\/li>\n<\/ul>\n\n\n\n
This ensures conservation of mass and atoms for each element across the equation.<\/p>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
