Overview of common digestive issues and their management.

It looks like you've uploaded an image containing a table with various substances and their properties, along with a task to classify them as pure substances or mixtures, and further classify the mixtures as homogeneous or heterogeneous.

Since I can't view images directly, I’ll guide you through how to solve this type of problem based on typical content in such tables. If you can provide the text from the image (e.g., the list of substances and their descriptions), I can give you a precise solution.

However, here’s how to approach this kind of classification:

🔹 Step-by-Step Guide to Classify Substances

#### 1. Pure Substance
- A substance that has a fixed composition and distinct chemical properties.
- Can be an element (like oxygen, gold) or a compound (like water, salt).
- Examples: Water (H₂O), iron, sugar.

#### 2. Mixture
- A combination of two or more substances that are not chemically bonded.
- Mixtures can be separated by physical means.

##### a. Homogeneous Mixture
- Uniform composition throughout.
- Examples: Saltwater, air, brass.

##### b. Heterogeneous Mixture
- Non-uniform composition; you can see different parts.
- Examples: Sand and water, salad dressing, granite.

🔹 How to Analyze Each Entry

For each item in your table:
1. Look at the description or name.
2. Ask:
- Is it a single element or compound? → Pure substance
- Is it a combination of substances that aren’t chemically bonded?
- Does it look uniform? → Homogeneous mixture
- Does it have visible differences? → Heterogeneous mixture

🔹 Example Classification

Let’s assume your table includes these entries (common examples):

| Substance | Description | Classification |
|----------|-------------|----------------|
| Saltwater | Dissolved salt in water | Homogeneous mixture |
| Air | Gases (N₂, O₂, etc.) | Homogeneous mixture |
| Sand and water | Visible particles in water | Heterogeneous mixture |
| Pure water | H₂O | Pure substance |
| Bronze | Copper and tin alloy | Homogeneous mixture |
| Chocolate chip cookie | Crumbs, chips, dough | Heterogeneous mixture |
| Oxygen gas | O₂ | Pure substance |
| Sugar | C₁₂H₂₂O₁₁ | Pure substance |

✔ Final Answer Format (Example)

If your task is to fill in a column for classification, it might look like:

| Substance | Classification |
|-------------------|----------------------------|
| Saltwater | Homogeneous mixture |
| Air | Homogeneous mixture |
| Sand and water | Heterogeneous mixture |
| Pure water | Pure substance |
| Bronze | Homogeneous mixture |
| Chocolate chip cookie | Heterogeneous mixture |
| Oxygen gas | Pure substance |
| Sugar | Pure substance |

📌 Please provide the actual text or list of substances from the image, and I will classify them exactly as per your table.

Alternatively, if you describe what's in the image (e.g., "the first row says 'milk' and describes it as 'a liquid with fat globules'"), I can help you classify each one.
