Does anyone know a website that will help me identify the physical properties of compounds, elements, and mixtures? For example, describe the physical characteristics of mercury (liquid).

Here is a site that give them all. Click on one element at a time.

Yes, there are several websites that can help you identify the physical properties of compounds, elements, and mixtures. One such website is PubChem (https://pubchem.ncbi.nlm.nih.gov/). Here's how you can use it to find the physical properties of mercury.

1. Open the PubChem website in your web browser.
2. In the search bar, type "mercury" and click on the search button.
3. On the search results page, you will see various entries for mercury. Look for the compound or element you are interested in. In this case, you can select the entry for "Mercury" (Chemical ID: 23931).
4. Click on the compound or element name (Mercury) to open its PubChem page.
5. On the PubChem page, you will find detailed information about mercury, including its physical properties.
6. Scroll down the page, and you will see a section titled "Physical Description." Here, you will find information about mercury's physical characteristics, such as its appearance, odor, state (liquid/solid), and other relevant properties.
7. You can also explore other sections on the page, such as "Chemical and Physical Properties" or "Safety and Hazards" to gather more information about mercury's physical properties.

By following these steps, you can use PubChem or similar websites to identify the physical properties of compounds, elements, and mixtures.
