Question

drag the tiles to the correct boxes to complete the pairs.
match the chemical name of each oxide of phosphorus to its chemical formula
phosphorus monoxide
p₄o₇
diphosphorus tetroxide
p₂o₅
tetraphosphorus heptoxide
p₂o₄
diphosphorus pentoxide
po

Explanation:

To match the chemical names of phosphorus oxides to their formulas, we use the naming rules for binary molecular compounds (prefixes indicate the number of atoms: mono-=1, di-=2, tetra-=4, hepta-=7, penta-=5).

• Phosphorus monoxide: "Mono-" for P (1) and "oxide" (O, 1) → Formula: \( \text{PO} \)
• Diphosphorus tetroxide: "Di-" (2 P) and "tetra-" (4 O) → Formula: \( \text{P}_2\text{O}_4 \)
• Diphosphorus pentoxide: "Di-" (2 P) and "penta-" (5 O) → Formula: \( \text{P}_2\text{O}_5 \)
• Tetraphosphorus heptoxide: "Tetra-" (4 P) and "hepta-" (7 O) → Formula: \( \text{P}_4\text{O}_7 \)

Answer:

• phosphorus monoxide \( \longleftrightarrow \) PO
• diphosphorus tetroxide \( \longleftrightarrow \) \( \text{P}_2\text{O}_4 \)
• diphosphorus pentoxide \( \longleftrightarrow \) \( \text{P}_2\text{O}_5 \)
• tetraphosphorus heptoxide \( \longleftrightarrow \) \( \text{P}_4\text{O}_7 \)
