* a proton donor
thaks for your help i will be waiting
These are given to you to think.
Is gasoline a hydrocarbon? Is vegetable oil a hydrocarbon?
what is perfume?
what is pickle juice (read the label)
volatile...what evaporates?
Figure out the rest. I hate giving you answers to these. You need to think.
thank you
Sure, I'd be happy to help you with your chemistry homework! Let's break it down step by step and think through each item together.
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 understanding the concept of molecular mass. Molecular mass is the sum of the atomic masses of all the atoms in a molecule. So, you can look for hydrocarbons that have larger and more complex structures, which will result in a higher molecular mass. For example, you can search for hydrocarbons like octane (C8H18) or even larger ones like tetradecane (C14H30), which will have molecular masses greater than 100 g/mol.
2. 2-propanol:
2-propanol, also known as isopropyl alcohol, is a common alcohol with the molecular formula C3H8O. You can find it in many stores, pharmacies, or online platforms. It is often used as a solvent or disinfectant.
3. An aromatic compound (in the chemistry context):
In chemistry, aromatic compounds refer to a specific type of organic compound that contains a delocalized ring of atoms with alternating single and double bonds. For example, benzene (C6H6) is a classic aromatic compound. You can try to find some products or chemicals labeled as aromatic, or look for compounds with benzene rings in their structure.
4. A liquid that has alum in it:
Alum is a common name for compounds that contain aluminum, such as aluminum sulfate (Al2(SO4)3). You can look for products or chemicals that mention the presence of alum on their labels or ingredients. Some examples could be certain antiperspirants or deodorants.
5. A volatile liquid:
In chemistry, volatility refers to the tendency of a substance to rapidly evaporate or vaporize at a relatively low temperature. Volatile liquids have low boiling points and readily transform into vapor. Examples of volatile liquids include alcohol, gasoline, or acetone. You can find these liquids in various products or chemicals, depending on their intended use.
6. 4 different crystalline substances:
Crystalline substances are those with a regular, repeating pattern of atoms or molecules that give them a distinct crystal structure. Many minerals and compounds can have crystalline forms. To find four different crystalline substances, you can consider various options like table salt (sodium chloride, NaCl), sugar (sucrose, C12H22O11), Epsom salt (magnesium sulfate, MgSO4), or quartz (silicon dioxide, SiO2). You can find these substances in stores, your kitchen pantry, or even in nature.
7. Something with L-carvone or D-carvone:
L-carvone and D-carvone are stereoisomers of a compound found in many natural sources, including spearmint and caraway seeds. These compounds have slightly different properties based on their molecular configurations. You can find products or botanical extracts that contain L-carvone or D-carvone. Examples include certain essential oils or flavorings used in food and beverages.
8. A non-electrolyte that dissolves in water:
A non-electrolyte is a substance that does not conduct electricity when dissolved in water. Typically, molecular compounds are non-electrolytes since they do not ionize in solution. For example, sugar (sucrose, C12H22O11) is a non-electrolyte that dissolves in water. You can find other molecular compounds like ethanol (C2H5OH) or glycerol (C3H8O3), which also dissolve in water without conducting electricity.
9. A polymer:
Polymers are large molecules made up of repeating subunits called monomers. They are commonly found in various products, including plastics, fibers, and coatings. You can find examples of polymers in everyday items like plastic water bottles (made of polyethylene terephthalate, PET) or synthetic rubber (made of polyisoprene).
10. Something with a pressure greater than 2.0 atmospheres:
To find something with a pressure greater than 2.0 atmospheres, you can search for pressurized containers or systems. Examples of such items include a pressurized aerosol can or a car tire. These often operate at higher pressures than atmospheric pressure (1.0 atmosphere).
11. Something with a pressure less than 2.0 atmospheres:
In contrast, to find something with a pressure less than 2.0 atmospheres, you can consider items operating in a vacuum or under reduced pressure conditions. For instance, certain laboratory vacuum pumps or vacuum-sealed packages typically function at pressures below atmospheric pressure.
12. A proton donor:
A proton donor refers to a substance that can donate a hydrogen ion (H+) in a chemical reaction. Substances that can readily donate protons are typically acids. Examples of proton donors include hydrochloric acid (HCl) or acetic acid (CH3COOH). You can find various acidic compounds in the form of household cleaning agents, vinegar, or some fruits.
Please note that while I can guide you through the process of finding these items, it's important to exercise caution and adhere to safety guidelines when handling potentially hazardous chemicals or substances. Always consult with a teacher, parent, or knowledgeable authority to ensure proper handling and disposal procedures.
