Which is not a property of a pure substance fixed composition uniform composition varying composition?
A pure substance has a fixed composition and uniform composition, meaning it consists of only one type of particle and its properties do not change regardless of the sample size. Therefore, varying composition is not a property of a pure substance, as it implies the presence of multiple substances or mixtures.
Which is not a property of a pure substance uniform composition varying composition fixed composition?
The property that is not characteristic of a pure substance is "varying composition." A pure substance has a fixed composition, meaning it has a consistent and definite chemical makeup throughout. In contrast, substances with varying composition are mixtures, which can contain different amounts and types of components.
What is a pure material called?
A pure material is called a substance. It is a form of matter that has uniform and definite composition, with distinct physical and chemical properties.
Is Hg a homogeneous or heterogenous?
Mercury (Hg) is a pure substance, so it is considered homogeneous because it has a uniform composition throughout.
Why is naphthalene a pure substance?
Naphthalene is considered a pure substance because it is a chemical compound made up of only naphthalene molecules. It has a definite and consistent chemical composition, with uniform properties throughout its structure.
Which is a property of a pure substance uniform composition fixed composition varying composition?
A property of a pure substance is fixed composition. This means that the substance is made up of only one type of molecule or atom throughout, with no variation in its chemical composition.
Which is not a property of a pure substance fixed composition uniform composition varying composition?
A pure substance has a fixed composition and uniform composition, meaning it consists of only one type of particle and its properties do not change regardless of the sample size. Therefore, varying composition is not a property of a pure substance, as it implies the presence of multiple substances or mixtures.
What is uniform composition?
a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
Which would not be classified as a pure substance?
A mixture would not be classified as a pure substance because it contains more than one type of substance, which are not chemically bonded together. Mixtures can be further classified as homogeneous (uniform composition) or heterogeneous (non-uniform composition).
Which is not a property of a pure substance uniform composition varying composition fixed composition?
The property that is not characteristic of a pure substance is "varying composition." A pure substance has a fixed composition, meaning it has a consistent and definite chemical makeup throughout. In contrast, substances with varying composition are mixtures, which can contain different amounts and types of components.
Is a table salt pure or a mixture?
Table salt is a pure substance. It is combined in such a way that it is uniform and definite in composition.
Is toluene a pure substance or mixture?
Toluene is a pure substance because it is a single compound with a uniform chemical composition throughout.
Is table salt a pure substance or mixture?
Table salt is a pure substance. It is combined in such a way that it is uniform and definite in composition.
Matter has a uniform and definite composition called what?
Substance, classified as an element and compound. For an element, it cannot be separated into another simplier substance; for a compound, it can be dicomposed into elements using chemical processes.
Is sulfur a pure substance?
Sulfur is a pure substance because it consists of only sulfur atoms and has a uniform chemical composition throughout. It is an element found on the periodic table with its own distinct properties.
What is a pure material called?
A pure material is called a substance. It is a form of matter that has uniform and definite composition, with distinct physical and chemical properties.
Can the terms heterogeneous and homogeneous be applied to pure substances as well as mixtures?
Yes, the terms heterogeneous and homogeneous can be applied to both pure substances and mixtures. A pure substance can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition), depending on its physical properties. Similarly, a mixture can also be classified as either homogeneous (uniform composition) or heterogeneous (non-uniform composition) based on the distribution of its components.
