Study Notes
Practical Applications
- Methane (CH4) has a tetrahedral molecular geometry with a central carbon atom bonded to four hydrogen atoms, contributing to its non-polar nature and symmetrical structure.
- Methane is widely used as a fuel source for heating and electricity generation due to its abundance and clean-burning properties.
Catalyst Applications
- Vanadium pentoxide (V2O5) has a trigonal planar molecular geometry, facilitating the release of reactive oxygen species during catalytic reactions.
- V2O5 is commonly used as a catalyst to promote the oxidation of pollutants such as nitrogen oxides (NO) and sulfur dioxide (SO2).
- By transferring oxygen atoms to the pollutant molecules, V2O5 facilitates oxidation reactions that convert the pollutants into less harmful or inert compounds.
Liquefied Petroleum Gas (LPG)
- Butane is often combined with propane to form LPG, which is commonly used as a fuel for various applications such as grilling stoves, cigarette lighters, torches, and space heaters.
- Adding butane to the propane mixture enhances the energy density of the LPG, providing more energy when burned.
Biomolecules
- Carbohydrates are the primary sources of energy for living organisms.
- Lipids are composed mainly of carbon (C), hydrogen (H), and oxygen (O), with a lower proportion of oxygen compared to carbohydrates.
- The basic unit of lipids is a fatty acid, consisting of a long hydrocarbon chain with a carboxylic acid group (-COOH) at one end.
- Fats and oils serve as efficient energy storage molecules in organisms.
- Nucleic acids, including DNA and RNA, store and transmit genetic information in living organisms.
- Nucleic acids are polymers composed of nucleotide monomers.
Polymers and Biomolecules
- Polyvinyl Chloride (PVC) is utilized in construction for pipes, window frames, flooring, and siding due to its durability, weather resistance, and flame retardancy.
Macronutrients
- Proteins are macronutrients found abundantly in foods such as meat, fish, eggs, dairy products, legumes, and nuts.
- These food groups are important sources of essential amino acids, which the body cannot synthesize on its own and must obtain from the diet.
