a chemical formula
CH3COOH is a pure substance. It is the chemical formula for acetic acid.
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
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.
Selenium is a pure chemical element.
Matter with a definite chemical makeup is a pure substance.

Pure substances fall into two categories: elements or compounds, both of which have constant compositions. H2O is a compound, and therefore a pure substance because its composition does not vary.

Uranium is a natural chemical element, a pure element.
Definite chemical makeup refers to the specific composition of a substance, characterized by a consistent ratio of elements and compounds that define its identity. This concept is fundamental in chemistry, as it distinguishes pure substances from mixtures. For example, water (H₂O) always consists of two hydrogen atoms and one oxygen atom, maintaining the same chemical properties regardless of its source. Understanding a substance's definite chemical makeup is crucial for predicting its behavior and interactions in chemical reactions.
Silver is a chemical Element - which means silver is a pure substance.
