Question

Accepted Answer

### 1. Nitrogen monoxide
# Explanation:
## Step1: Identify the elements and prefixes.
Nitrogen monoxide consists of nitrogen (N) and oxygen (O). The prefix "mono-" indicates one oxygen atom.
## Step2: Write the formula.
The formula for nitrogen monoxide is $NO$.
# Answer: $NO$

### 2. $\boldsymbol{N_2O_5}$
# Explanation:
## Step1: Identify the elements and subscripts.
The compound has nitrogen (N) with subscript 2 and oxygen (O) with subscript 5.
## Step2: Name using prefixes.
For 2 nitrogen atoms, use "di-", and for 5 oxygen atoms, use "penta-". So the name is dinitrogen pentoxide.
# Answer: Dinitrogen pentoxide

### 3. Hydrofluoric acid
# Explanation:
## Step1: Recall the formula for hydrofluoric acid.
Hydrofluoric acid is an acid formed from hydrogen (H) and fluorine (F).
## Step2: Write the formula.
The formula is $HF$.
# Answer: $HF$

### 4. $\boldsymbol{H_3PO_4}$
# Explanation:
## Step1: Identify the acid type.
$H_3PO_4$ is a ternary acid (contains H, P, O). The anion is phosphate ($PO_4^{3 - }$).
## Step2: Name the acid.
When the anion is phosphate, the acid is named phosphoric acid.
# Answer: Phosphoric acid

### 5. Carbon tetrachloride
# Explanation:
## Step1: Identify the elements and prefix.
Carbon (C) and chlorine (Cl). The prefix "tetra-" indicates 4 chlorine atoms.
## Step2: Write the formula.
The formula is $CCl_4$.
# Answer: $CCl_4$

### 6. $\boldsymbol{H_2SO_3}$
# Explanation:
## Step1: Identify the acid type.
$H_2SO_3$ is a ternary acid. The anion is sulfite ($SO_3^{2 - }$).
## Step2: Name the acid.
When the anion is sulfite, the acid is named sulfurous acid.
# Answer: Sulfurous acid

### 7. Dihydrogen monoxide
# Explanation:
## Step1: Identify the elements and prefixes.
"Dihydrogen" means 2 hydrogen atoms, "monoxide" means 1 oxygen atom.
## Step2: Write the formula.
The formula is $H_2O$.
# Answer: $H_2O$

### 8. Sulfuric acid
# Explanation:
## Step1: Recall the formula for sulfuric acid.
Sulfuric acid is formed from hydrogen (H), sulfur (S), and oxygen (O). The anion is sulfate ($SO_4^{2 - }$).
## Step2: Write the formula.
The formula is $H_2SO_4$.
# Answer: $H_2SO_4$

### 9. $\boldsymbol{PCl_5}$
# Explanation:
## Step1: Identify the elements and subscripts.
Phosphorus (P) with subscript 1 and chlorine (Cl) with subscript 5.
## Step2: Name using prefixes.
For 1 phosphorus (no prefix needed), and for 5 chlorine atoms, use "penta-". So the name is phosphorus pentachloride.
# Answer: Phosphorus pentachloride

### 10. $\boldsymbol{HClO_3}$
# Explanation:
## Step1: Identify the acid type.
$HClO_3$ is a ternary acid. The anion is chlorate ($ClO_3^ - $).
## Step2: Name the acid.
When the anion is chlorate, the acid is named chloric acid.
# Answer: Chloric acid
