Question

3 select the correct answer. what is the chemical name of the covalent compound p₄o₉? a. tetraphosphorus nonaoxygen b. tetraphosphate nonoxygen c. tetraphosphide nonaoxide d. tetraphosphorus nonoxide

Explanation:

When naming covalent compounds, the prefixes indicate the number of atoms. For \(P_4O_9\), 'tetra -' is the prefix for 4 (as in \(P_4\), so 'tetraphosphorus'), and 'nona -' is the prefix for 9 (for \(O_9\), and the ending for oxygen in such compound names is '-oxide', so 'nonoxide').

Answer:

D. tetraphosphorus nonoxide
