Question

naming covalent compounds worksheet
write the formulas for the following covalent compounds:

1. antimony tribromide
2. hexaboron silicide
3. chlorine dioxide
4. hydrogen iodide
5. iodine pentafluoride
6. dinitrogen trioxide
7. ammonia
8. phosphorus triiodide

Explanation:

Step1: Analyze prefixes and elements

• For "antimony tribromide": "antimony" is Sb, "tri - " means 3, "bromide" is Br. So formula is $\text{SbBr}_3$.
• For "hexaboron silicide": "hexa - " means 6 (B), "silicide" is Si. Formula is $\text{B}_6\text{Si}$.
• For "chlorine dioxide": "di - " means 2 (O), Cl is chlorine. Formula is $\text{ClO}_2$.
• For "hydrogen iodide": H and I. Formula is $\text{HI}$.
• For "iodine pentafluoride": "penta - " means 5 (F), I is iodine. Formula is $\text{IF}_5$.
• For "dinitrogen trioxide": "di - " (N), "tri - " (O). Formula is $\text{N}_2\text{O}_3$.
• For "ammonia": It has a special formula $\text{NH}_3$.
• For "phosphorus triiodide": "tri - " (I), P is phosphorus. Formula is $\text{PI}_3$.

Answer:

1. $\text{SbBr}_3$
2. $\text{B}_6\text{Si}$
3. $\text{ClO}_2$
4. $\text{HI}$
5. $\text{IF}_5$
6. $\text{N}_2\text{O}_3$
7. $\text{NH}_3$
8. $\text{PI}_3$
