Problem: Naming Inorganic Compounds and Acids Worksheet (CHM 50)

#### Section 1: Provide acceptable IUPAC names for the following compounds.

To solve this section, we need to identify the type of compound (binary ionic, ternary ionic, binary molecular, binary acid, or ternary oxyacid) and apply the appropriate naming rules.

---

#### a) LiBr
- Type: Binary ionic compound
- Naming Rule: The name is "metal + nonmetal ion."
- Name: Lithium bromide

---

#### b) KNO₃
- Type: Ternary ionic compound (nitrate salt)
- Naming Rule: The name is "metal + polyatomic ion."
- Name: Potassium nitrate

---

#### c) BrF₃
- Type: Binary molecular compound
- Naming Rule: Use prefixes for the number of atoms and end with "-ide."
- Name: Bromine trifluoride

---

#### d) HI (aq)
- Type: Binary acid
- Naming Rule: For acids, use "hydro-" + root of nonmetal + "-ic acid."
- Name: Hydroiodic acid

---

#### e) H₂CO₃ (aq)
- Type: Ternary oxyacid
- Naming Rule: Use the root of the central atom + "-ic acid" (for -ate) or "-ous acid" (for -ite).
- Name: Carbonic acid

---

#### f) MnCl₂
- Type: Binary ionic compound
- Naming Rule: The name is "metal + nonmetal ion." Since manganese can have multiple oxidation states, specify the charge using Roman numerals.
- Name: Manganese(II) chloride

---

#### g) H₂S (aq)
- Type: Binary acid
- Naming Rule: Use "hydro-" + root of nonmetal + "-ic acid."
- Name: Hydrosulfuric acid

---

#### h) I₂O₄
- Type: Ternary oxyacid
- Naming Rule: Use the root of the central atom + "-ic acid" (for -ate) or "-ous acid" (for -ite). Here, it's an iodate compound.
- Name: Iodic acid

---

#### i) Na₃N
- Type: Binary ionic compound
- Naming Rule: The name is "metal + nonmetal ion."
- Name: Sodium nitride

---

#### j) CO₂
- Type: Binary molecular compound
- Naming Rule: Use prefixes for the number of atoms and end with "-ide."
- Name: Carbon dioxide

---

#### k) Cu(ClO₂)₂
- Type: Ternary ionic compound (with a polyatomic ion)
- Naming Rule: The name is "metal + polyatomic ion." Copper has multiple oxidation states, so specify the charge using Roman numerals.
- Name: Copper(II) chlorite

---

#### l) HClO₄ (aq)
- Type: Ternary oxyacid
- Naming Rule: Use the root of the central atom + "-ic acid" (for -ate) or "-ous acid" (for -ite). Here, it's perchloric acid.
- Name: Perchloric acid

---

#### m) Cl₂O₃
- Type: Binary molecular compound
- Naming Rule: Use prefixes for the number of atoms and end with "-ide."
- Name: Dichlorine trioxide

---

#### n) Al₂(Cr₂O₇)₃
- Type: Ternary ionic compound (with a polyatomic ion)
- Naming Rule: The name is "metal + polyatomic ion." Aluminum is always +3, but chromium(VI) is in the dichromate ion.
- Name: Aluminum dichromate

---

#### o) Mg(ClO₄)₂
- Type: Ternary ionic compound (with a polyatomic ion)
- Naming Rule: The name is "metal + polyatomic ion."
- Name: Magnesium perchlorate

---

#### p) CrP
- Type: Binary ionic compound
- Naming Rule: The name is "metal + nonmetal ion." Chromium can have multiple oxidation states, so specify the charge using Roman numerals.
- Name: Chromium(III) phosphide

---

#### q) HNO₂ (aq)
- Type: Ternary oxyacid
- Naming Rule: Use the root of the central atom + "-ic acid" (for -ate) or "-ous acid" (for -ite). Here, it's nitrous acid.
- Name: Nitrous acid

---

#### r) H₂SO₃ (aq)
- Type: Ternary oxyacid
- Naming Rule: Use the root of the central atom + "-ic acid" (for -ate) or "-ous acid" (for -ite). Here, it's sulfurous acid.
- Name: Sulfurous acid

---

#### s) HCl
- Type: Binary acid
- Naming Rule: Use "hydro-" + root of nonmetal + "-ic acid."
- Name: Hydrochloric acid

---

#### t) H₂Se (aq)
- Type: Binary acid
- Naming Rule: Use "hydro-" + root of nonmetal + "-ic acid."
- Name: Hydroselenic acid

---
