1. Here is the information on the chemical formula, characteristics, and uses of the substances:
- Methane (CH4): Methane is a colorless and odorless gas. It is the simplest hydrocarbon and the main component of natural gas. It is used as a fuel for heating, cooking, and electricity generation.
- Salt (NaCl): Salt is a crystalline compound composed of sodium (Na) and chlorine (Cl) ions. It is commonly used as a seasoning in food and for food preservation. It also has various industrial uses, such as in the production of chemicals and in water treatment.
- Ethyne (C2H2): Ethyne, also known as acetylene, is a colorless gas with a distinct odor. It is highly flammable and is used in welding and cutting torches due to its high heat intensity. It is also used in the production of various chemicals, including plastics and solvents.
- Benzene (C6H6): Benzene is a colorless liquid with a sweet aroma. It is an aromatic hydrocarbon and is used as a starting material for the production of many chemicals, including plastics, synthetic fibers, and detergents.
- Water (H2O): Water is a transparent and odorless liquid. It is essential for all known forms of life and has various uses, including drinking, cooking, cleaning, and industrial processes.
- Ammonia (NH3): Ammonia is a colorless gas with a pungent odor. It is used in various industries, such as in the production of fertilizers, cleaning agents, and refrigerants.
2. Based on the research, these substances can be classified as follows:
- Methane, ethyne, benzene, and ammonia are organic compounds.
- Salt and water are inorganic compounds.
3. The basis of this classification is the presence or absence of carbon atoms in the chemical structure. Organic compounds contain carbon atoms bonded to hydrogen atoms, while inorganic compounds do not have carbon-hydrogen bonds.
4. Yes, the chemical formula can help in classifying substances. Organic compounds generally have chemical formulas that include carbon (C) atoms, while inorganic compounds may not contain carbon.
5. The substances considered organic are methane, ethyne, benzene, and ammonia.
6. Organic compounds differ from inorganic compounds based on their chemical composition. Organic compounds contain carbon atoms bonded to hydrogen atoms, along with other elements such as oxygen, nitrogen, sulfur, and halogens. Inorganic compounds, on the other hand, do not contain carbon-hydrogen bonds and can include minerals, metals, and nonmetals. Organic compounds are typically associated with living organisms and have complex structures, while inorganic compounds can be naturally occurring minerals or synthetic compounds.
