Question

1. give the correct chemical name for the following chemical formula: p₅o₉.

Explanation:

For naming covalent compounds like \(P_5O_9\), we use prefixes to indicate the number of each atom. The prefix for 5 is "penta -" (for phosphorus, \(P\)) and for 9 is "nona -" (for oxygen, \(O\)). The ending of the second element (oxygen) is changed to "-ide". So, combining these, we get pentaphosphorus nonoxide.

Answer:

Pentaphosphorus nonoxide
