It looks like you've uploaded an image of a
lab assignment titled *"LABORATORY PRACTICE"* focused on
chemical nomenclature, specifically the naming of
inorganic compounds. However, I can't view or access images directly. But based on your description and the text visible in your message, I can help you solve the problem if you provide the
specific task or question from the image.
Here’s what I see in the text:
---
Lab Practice Overview:
- The lab is about
naming inorganic compounds.
- It involves
practical exercises to practice
chemical nomenclature (naming rules for ionic and covalent compounds).
- There are two main sections:
1.
Nomenclature of Ionic Compounds
- Includes naming binary ionic compounds (e.g., NaCl), with attention to transition metals (which may have variable charges).
- Uses
stock system (e.g., iron(III) chloride).
-
Nomenclature of Covalent Compounds
- For molecular compounds (e.g., CO₂), using prefixes like *mono-, di-, tri-*.
- Students are expected to:
- Name compounds given formulas.
- Write formulas from names.
- Use periodic table and rules for naming.

Common Tasks in Such Labs:
1.
Name the following compounds:
- Example: FeCl₃ → Iron(III) chloride
- Example: N₂O₄ → Dinitrogen tetroxide
2.
Write formulas for named compounds:
- Example: Aluminum sulfate → Al₂(SO₄)₃
3.
Determine oxidation states.
4.
Fill out tables matching names and formulas.
5.
Answer questions about naming conventions.

How I Can Help:
Please tell me:
- What specific
problem or question is in the image?
- Are you asked to name compounds? Write formulas?
- Is there a table to complete?
Once I know the exact task, I’ll walk you through the
step-by-step solution with explanations.
For example, if the task is:
> "Name the compound: CuSO₄"
I would explain:
- Copper is a transition metal — it can have multiple charges.
- SO₄²⁻ is sulfate, charge = -2.
- So Cu must be +2 to balance.
- Therefore, name:
Copper(II) sulfate.
Let me know the actual task!
