What is a characteristics of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
What is a characteristic of pure substance?
A pure substance contains only one chemical identity, e.g. one element or one compound. While the properties of any pure substance might be completely different from that of another, the properties of any sample of a single pure substance will always be the same.
What are some physical properties are constant for pure substances?
This has lots of answers; some of them are: malleability chemical properties electrical properties color texture I suspect there are more because the size of something rarely changes the intrinsic properties of that something.
What is a substance with a constant composition?
No substance always has the same composition and properties, unless that substance is only considered in one of the various phases of matter. An element would be the logical choice, but many compounds and even solutions are the same no matter what (of course dependent on phase).
Is CH3COOH a pure substance?
It can be, if it is 100% pure. (Technically speaking, this is a difficult thing to do, in practice, because minute impurities almost always exist. 99.99999% purity is usually considered "pure".)
Is the difference between a pure substance and a mixture always easy to observe?
Frequently it is not possible.

What kind of substance always has properties that are hard to see?
For example very rare radioactive chemical elements.
Is the mixing of iron and sulfur a physical change or chemical change?
It is always categorized as a Physical change as no new substance with different properties forms.
Did Georgia always observe Daylight Saving Time?
Georgia did not always observe daylight saving time.

What are the properties of matters?
PROPERTIES OF MATTER 1. A Substance may be identified by certain Qualities, or Traits. A QUALITY OR TRAIT THAT IDENTIFIES A SUBSTANCE IS CALLED A PROPERTY. 2. The property of a substance stays the SAME even if the Volume changes. 3. COLOR, MASS, SMALL, DENSITY, AND COMPOSITION ARE ALL EXAMPLES OF PROPERTIES THAT CAN HELP SCIENTIST IDENTIFY SUBSTANCES. 4. A PROPERTY THAT ALWAYS STAYS THE SAME IS CALLED A CHARACTERISTIC PROPERTY BECAUSE IT IS A CHARACTERISTIC OF A PARTICULAR KIND OF MATTER. 5. EVERY SUBSTANCE HAS TWO KINDS OF PROPERTIES - PHYSICAL PROPERTIES AND CHEMICAL PROPERTIES. 6. A PHSICAL PROPERTY is a property of matter that can be OBSERVED or MEASURED WITHOUT CHANGING the composition of the substance. 7. Physical properties are often used to identify substances. 8. SOME PHYSICAL PROPERTIES OF MATTER: A. BIOLING POINT - The temperature at which a substance changes from a liquid to a gas. B. CONDENSATION POINT - The temperature at which a substance changes from a gas to liquid; same temperature as boiling point. C. DENSITY - The mass of a specific volume of substance. D. FREEZING POINT - The temperature at which a substance changes from a liquid to a solid; same temperature as melting point. E. MELTING POINT - The temperature at which a substance changes from a solid to a liquid. F. RESISTANCE - The opposition of a substance has to the flow of electric current. G. SOLUBILITY - The degree to which a substance will dissolve in a given amount of another substance, such as water.
What is the smallest unit of substances that keeps all of the physical and chemical properties of that substance?
The atom or smaller, the amount of protons like helium always has 2 protons no matter what.
Molecules in an object or substance are always in?
Molecules in an object or substance are always in motion.
What is a substance with a constant composition?
No substance always has the same composition and properties, unless that substance is only considered in one of the various phases of matter. An element would be the logical choice, but many compounds and even solutions are the same no matter what (of course dependent on phase).
