Question

question 10 (1 point) listen the correct formulas for the binary covalent compounds tetraiodide hexafluoride and pentaphosphorous heptoxide are: 1) i₇f₃ and p₆o₄ 2) i₄f₆ and p₅o₇ 3) i₅f₆ and p₇o₇ 4) i₃f₇ and p₄o₆

Explanation:

Step1: Analyze Tetraiodide Hexafluoride

The prefix "tetra-" means 4, so iodine (I) has a subscript of 4. The prefix "hexa-" means 6, so fluorine (F) has a subscript of 6. So the formula should be \( I_4F_6 \).

Step2: Analyze PentaPhosphorous Heptoxide

The prefix "penta-" means 5, so phosphorous (P) has a subscript of 5. The prefix "hepto-" (hept-) means 7, so oxygen (O) has a subscript of 7. So the formula should be \( P_5O_7 \).

Step3: Match with Options

Looking at the options, option 2 has \( I_4F_6 \) and \( P_5O_7 \), which matches our derived formulas.

Answer:

1. \( I_4F_6 \) and \( P_5O_7 \)
