Octane is the only thing that can be decomposed by chemical means.
physical or chemical? physical property: sucrose is sweet while sodium chloride is salty, sucrose is often prepared as fine, crystalline powder while sodium chloride is often prepared with larger crystals. chemical property: sucrose is made up of molecules while sodium chloride is made up of ions. sucrose when dissolved in water cannot conduct electricity because it has covalent bonds. thus there are no mobile ions or electrons to conduct electricity. sodium chloride on the other hand has mobile ions when dissolved in water. thus it can conduct electricity.
An element is a pure substance that cannot be broken down into other substances by chemical means. Each element is made up of only one type of atom. Examples of elements include oxygen, carbon, and gold.
Elements
A mineral is a naturally occurring substance that is solid and stable at room temperature, representable by a chemical formula, usually abiogenic, and has an ordered atomic structure- Definition from Wikipedia. Glucose and fructose are monosaccharide sugars. A monosaccharide is the smallest unit of sugar, mono meaning 1. Sucrose is commonly called table sugar and is a disaccharide. A disaccharide is a sugar that is made up of two sugar units, di meaning 2. Sucrose is produced as glucose and fructose are joined together by a condensation reaction. In the process a water molecule is eliminated. See the following equation. C6H12O6 + C6H12O6 => C12H22O11 + H2O glucose + fructose => sucrose + water This process does not occur spontaneously in nature. So we cannot define it as a mineral.
Sodium is a pure element and cannot be broken down by chemical means into simpler substances like water, ethanol, or sucrose. It is a fundamental building block of matter with its own unique properties and cannot be further decomposed through chemical reactions.
Sucrose can be decomposed chemically as it is a compound composed of carbon, hydrogen, and oxygen atoms. Sodium is an element, and ethanol is a compound made of carbon, hydrogen, and oxygen atoms, but water is a compound that cannot be decomposed chemically as it is already in its simplest form.
Carbon that cannot be decomposed is a chemical property. It is related to the chemical bonds and composition of the substance, indicating that the carbon atoms are tightly held together in a way that resists decomposition through physical means.
The substance is a chemical element.
Octane is the only thing that can be decomposed by chemical means.
No, aluminum cannot be decomposed into simpler substances. It is an element with the atomic number 13 and cannot be broken down into simpler materials by ordinary chemical reactions.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Carbon is classified as an element because it consists of only one type of atom, which cannot be decomposed into simpler substances using chemical methods.
No, hydrofluoric acid (HF) cannot be decomposed by a chemical change because it is a stable compound. Physical methods are typically used to separate HF into its constituent elements.
If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a periodic table).A chemical element cannot be decomposed into a simpler substance.Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
Ne - neon, is an element and also a noble gas. It can not be decomposed by a chemical reaction. All the other substances can be.
Mercury is an element with the atomic number 80, which means it consists of only one type of atom: mercury atoms. Elements are the simplest form of matter and cannot be broken down into simpler substances through chemical reactions. Therefore, mercury cannot be decomposed into simpler substances because it is already in its simplest form.
