Question

write the formula for each compound. capitalization and subscripts are graded. selenium tetrafluoride: oxygen difluoride: dinitrogen monoxide: phosphorus trichloride:

Explanation:

Step1: Analyze selenium tetrafluoride

The prefix "tetra -" means 4. Selenium is Se and fluorine is F. So the formula is SeF₄.

Step2: Analyze oxygen difluoride

The prefix "di -" means 2. Oxygen is O and fluorine is F. So the formula is OF₂.

Step3: Analyze dinitrogen monoxide

The prefix "di -" means 2 for nitrogen (N) and "mono -" means 1 for oxygen (O). So the formula is N₂O.

Step4: Analyze phosphorus trichloride

The prefix "tri -" means 3. Phosphorus is P and chlorine is Cl. So the formula is PCl₃.

Answer:

selenium tetrafluoride: SeF₄
oxygen difluoride: OF₂
dinitrogen monoxide: N₂O
phosphorus trichloride: PCl₃
