* a polymer
*something with a pressure greater than 2.0 atmospheres
*something with a pressure less than 2 atmospheres
* a proton donor
thaks for your help i will be waiting

Sure, I'd be happy to help you with your chemistry homework!

1. **A hydrocarbon with a molecular mass greater than 100 g/mol**: To find a hydrocarbon with a molecular mass greater than 100 g/mol, you can start by looking at the atomic masses of common elements in hydrocarbons, such as carbon (C) and hydrogen (H). Calculate the molecular mass by adding up the atomic masses of each atom in the hydrocarbon. You can use the periodic table to find the atomic masses. Once you find a suitable hydrocarbon, you can place it in a ziploc bag.

2. **2-propanol**: 2-propanol, also known as isopropyl alcohol, is a common chemical compound used as a solvent and disinfectant. You can easily purchase this compound at a drugstore or a chemical supply store. Make sure to check the label to confirm that it is indeed 2-propanol before adding it to your ziploc bag.

3. **An aromatic compound (in the chemistry sense)**: Aromatic compounds in chemistry refer to cyclic compounds that possess a specific type of electronic structure called aromaticity. One example of an aromatic compound is benzene (C6H6). You can find benzene or other aromatic compounds at a chemical supply store or consult your chemistry textbook to identify other examples.

4. **A liquid that has alum in it**: Alum is a commonly used compound in daily life, especially as a food additive and in water purification. A specific example of a liquid with alum is "alum solution." You can find alum solution at a grocery store or a chemical supply store. Remember to check the label to ensure it contains alum before adding it to your ziploc bag.

5. **A volatile liquid**: A volatile liquid is one that easily evaporates at room temperature and atmospheric pressure. An example is ethanol (C2H5OH). You can find this liquid at a liquor store or a chemical supply store. Ensure that the ethanol is suitable for scientific purposes and is labeled correctly before adding it to your ziploc bag.

6. **4 different crystalline substances**: Crystalline substances are solids that have a regular and repeating arrangement of atoms or molecules. Examples of crystalline substances include table salt (NaCl), sugar (C12H22O11), and quartz (SiO2). You can look for these substances in your kitchen or consult a chemical supply store to find a variety of crystalline substances to include in your ziploc bag.

7. **Something with L-carvone or D-carvone**: L-carvone and D-carvone are stereoisomers of each other and can be found in essential oils such as spearmint and caraway. You can purchase essential oils containing L-carvone or D-carvone at a health food store or a chemistry supplier. Ensure that the essential oil is labeled correctly and contains the desired stereoisomer before adding it to your ziploc bag.

8. **A non-electrolyte that dissolves in water**: Non-electrolytes are substances that do not conduct electricity when dissolved in water. Examples of non-electrolytes include sugar (C12H22O11) and alcohol (such as ethanol, C2H5OH). You can find sugar or alcohol at a grocery store or a chemical supply store to include in your ziploc bag.

9. **A polymer**: Polymers are large molecules made up of repeating subunits called monomers. Examples of polymers include polyethylene (used in plastic bags), polypropylene (used in water bottles), and polyvinyl chloride (used in piping). You can find polymer samples at a chemical supply store or even repurpose plastic products to include in your ziploc bag.

10. **Something with a pressure greater than 2.0 atmospheres**: High-pressure substances are typically found in industrial settings. However, you can find compressed gas cylinders at specialty stores or consult chemical suppliers for substances that are stored under high pressure. Ensure you follow proper safety guidelines when handling high-pressure substances.

11. **Something with a pressure less than 2 atmospheres**: Substances with pressure lower than 2 atmospheres are more commonly found in everyday environments. Examples include aerosol cans, gas cartridges, or manually pressurized containers used for cooking or gardening. These can be found at a local supermarket or other retail stores.

12. **A proton donor**: A proton donor can be an acid. Some common examples of proton donors (acids) are vinegar (acetic acid), lemon juice (citric acid), or hydrochloric acid (HCl). Please exercise caution and adhere to safety protocols when handling acids. You can find these substances at a supermarket or a chemical supply store.

Remember to exercise caution when handling chemicals, follow safety guidelines, and consult with your teacher for any specific requirements regarding your chemistry homework.
