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.
Is water a non-uniform example?
No, water is a uniform substance because it has the same chemical composition and properties throughout when in its liquid form.
Is toluene a pure substance or mixture?
Toluene is a pure substance because it is a single compound with a uniform chemical 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.
How do you determine whether a system is a subs or homogeneous mixt?
A mixture is homogeneous if its composition and properties are uniform throughout. A substance is a subset of mixtures, characterized by having uniform composition only. To determine if a system is a mixture or a substance, you would need to analyze its physical and chemical properties for uniformity.
Define pure substance?
A pure substance is a material made of only one type of particle, element, or compound. It has uniform and constant physical and chemical properties, meaning it does not vary in composition or characteristics throughout the sample.
A substance maintaining a uniform appearance and composition is a?
A substance maintaining a uniform appearance and composition is a homogeneous mixture. In a homogeneous mixture, the components are evenly distributed throughout the mixture and cannot be easily distinguished.
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.
Is pure substance uniform composition?
Yes, a pure substance has a uniform and definite composition. It is made up of only one type of element or compound, with consistent proportions of its constituent particles. This uniformity distinguishes pure substances from mixtures, which can contain multiple substances in varying proportions.
Is chromium heterogeneous or homogeneous?
Chromium is a chemical element that is naturally found as a solid in its metallic form. It is considered a homogeneous substance because it has the same uniform composition throughout its structure.
What is a matter with identical properties throughout?
A substance with identical properties throughout is called a pure substance. Examples include elements (e.g. gold, oxygen) and compounds (e.g. water, salt) that are uniform in composition and have consistent physical and chemical characteristics.
Is TNT a heterogenous or homogenous substance?
TNT (trinitrotoluene) is a homogeneous substance. It is a yellow crystalline powder with uniform composition throughout.
