Thank you! ### Chemistry Nomenclature Exercise#### Question 131The formulas and common names for several substances are given below. Provide the systematic names for these substances:a. **Pb(C\(_2\)H\(_3\)O\(_2\))\(_2\)** Common Name: Sugar of leadb. **CuSO\(_4\)** Common Name: Blue vitriolc. **CaO** Common Name: Quicklimed. **MgSO\(_4\)** Common Name: Epsom salts#### Question 132Each of the following compounds is incorrectly named. Identify what is wrong with each name, and provide the correct name for each compound:a. **FeCl\(_2\)** Incorrect Name: Iron chlorideb. **N\(_2\)O\(_4\)** Incorrect Name: Nitrogen(IV) oxidec. **CaO** Incorrect Name: Calcium(II) monoxided. **Al\(_2\)S\(_3\)** Incorrect Name: Dialuminum trisulfidee. **Mg(C\(_2\)H\(_3\)O\(_2\))\(_2\)** Incorrect Name: Manganese diacetatef. **Fe\(_3\)P\(_2\)** Incorrect Name: Iron(II) phosphideg. **P\(_4\)S\(_5\)** Incorrect Name: Phosphorus sulfideh. **Na\(_2\)O\(_2\)** Incorrect Name: Sodium oxide---This exercise helps in understanding the correct systematic naming of chemical compounds according to IUPAC norms, reinforcing key concepts in chemical nomenclature. **Exercise 157: Understanding Caffeine's Molecular Structure**Consider the following computer-generated model of caffeine. This model visually represents the arrangement of atoms within a caffeine molecule using a space-filling model.**Color Key:**- **Light Blue (H):** Hydrogen atoms- **Red (O):** Oxygen atoms- **Blue (N):** Nitrogen atoms- **Dark Grey (C):** Carbon atomsThe diagram displays how these atoms are bonded together in the molecular structure of caffeine. Each colored sphere represents a specific type of atom and its spatial orientation within the molecule.**Task:** Draw a Lewis structure for caffeine in which all atoms have a formal charge of zero.The objective is to practice creating a Lewis structure that accurately represents the bonding and electron arrangement in caffeine, ensuring formal charges are balanced across the molecule.
