When elements chemically combine which best describes the resulting compound?
When elements chemically combine, they form a compound that has distinct properties different from those of the individual elements. This new substance is characterized by a fixed ratio of atoms, resulting in a specific molecular structure and chemical behavior. The properties of the compound, such as boiling point, melting point, and reactivity, can vary significantly from those of the constituent elements.
What physical and chemical properties would you expect to find in two different samples of a pure substance?
Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.
What are 2 intensive properties of chlorine?
Two intensive properties of chlorine are its boiling point and density. The boiling point of chlorine is approximately -34.04 degrees Celsius, while its density is about 3.214 g/L at standard temperature and pressure. These properties are characteristic of chlorine and do not change regardless of the amount of the substance present.
What are the intrinsic or intensive?
Intrinsic properties are characteristics that do not change regardless of the amount or size of the material, such as density or boiling point. Intensive properties are also independent of the amount of material present, such as temperature or pressure.
What are properties that are unique to a substance?
Unique properties of a substance, often referred to as its "characteristic properties," include its boiling point, melting point, density, solubility, and specific heat capacity. These properties are intrinsic to the substance and can help identify it, regardless of the amount present. For example, water has a boiling point of 100°C at standard atmospheric pressure, which distinguishes it from other liquids. Additionally, chemical properties, such as reactivity with acids or bases, also contribute to a substance's uniqueness.
What are 3 intensive physical properties?
Density, melting point, and boiling point are three examples of intensive physical properties. These properties do not depend on the amount of substance present and are useful for identifying and characterizing materials.
What are non-examples of properties?
chemical properties are to do with how it acts chemically- so: polar vs Non polar PH / Pka melting point / boiling point Therefore non-examples would be its molecular mass/ geometry / atomical structure... although some of these would surely contribute to its chemical properties.

Is it true or false that characteristic properties of elements do not depend on the amount of material present in a sample of the element?
True. Characteristic properties of elements, such as melting point, boiling point, density, and chemical reactivity, do not depend on the amount of material present in a sample of the element. These properties are unique to each element and remain constant regardless of the quantity of the substance.
What does a compound look like and how can it be identified?
A compound is a substance made up of two or more different elements chemically bonded together. Compounds can be identified by their unique chemical formula, which shows the types and ratios of elements present in the compound. Additionally, compounds often have distinct physical properties, such as melting point, boiling point, and color, that can help in their identification.
What is the difference between equivalent point and end point in analytical chemistry?
The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte. The end point is the point in a titration when a physical change occurring immediate after the equivalence point
Where is the equivalence point located on a titration curve?
The equivalence point on a titration curve is located at the point where the amount of titrant added is stoichiometrically equivalent to the amount of analyte present in the solution.
Is conductivity intensive property?
Conductivity is an intensive property. Intensive properties are associated with the physical properties of a substance, and include things like melting point, ductility, malleability, density, and freezing point. These are characteristics of a substance that do not depend on the amount of the matter present.
What are 3 intensive properties of boron?
Three intensive properties of boron are its melting point (2349 K), density (2.34 g/cm³), and atomic number (5). These properties do not depend on the amount of boron present, making them intensive.
What are 2 intensive properties of chlorine?
Two intensive properties of chlorine are its boiling point and density. The boiling point of chlorine is approximately -34.04 degrees Celsius, while its density is about 3.214 g/L at standard temperature and pressure. These properties are characteristic of chlorine and do not change regardless of the amount of the substance present.
