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.
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 the property that is a quality of a substance that never changes and can be used to indentify the substance?
A quality of a substance that never changes is one of the reasons why density is a characteristic property
Is density a chemical property or a chemical property?
Density is classified as a physical property because the density of a substance can change when the substance changes state. Example: When water evaporates it is a physical change and the density changes. A chemical property is a property that describes its ability to react chemically with other substances and THEREFORE density is not a chemical property.
