What properties refer to a substance's ability to undergo changes that alter its composition and identity?
Chemical changes
Is a chemical composition and chemical properties the same thing?
No, a chemical composition refers to the types and ratios of elements present in a substance, whereas chemical properties describe how a substance behaves or reacts with other substances. Chemical properties include characteristics such as reactivity, stability, flammability, and toxicity.
What is any matter that has a fixed composition and definite properties?
You think probable to a chemical compound. But today the theory of the fixed composition is not generally valid.
What is a sample if matter that has the same composition and properties throughout what?
"A phase is a state of a...system that has...uniform chemical composition and physical properties.""Matter." Wikipedia. 19 Feb 2008, 04:16 UTC. Wikimedia Foundation, Inc. 19 Feb 2008 .
What does physical properties mean?
Physical properties can be observed or measured without changing the composition of matter
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What same fixed composition and properties is known as a?
substance
Matter that has the same composition and properties throughtout?
Substance
What properties refer to a substance's ability to undergo changes that alter its composition and identity?
Chemical changes
Composite definition in chemistry?
that deals with the composition and properties of substance and various elementary forms of matter ;study of matter, its substance, structure, properties, and reaction
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
No. In a physical change, the substance maintains its chemical composition.
Is a chemical composition and chemical properties the same thing?
No, a chemical composition refers to the types and ratios of elements present in a substance, whereas chemical properties describe how a substance behaves or reacts with other substances. Chemical properties include characteristics such as reactivity, stability, flammability, and toxicity.
What things are physical properties?
Physical propety is a characteristic of a substance that can be determined without changing the composition of that substance.
Sample of matter that has the same composition and properties throughout?
term for that is pure substance
A substance always has properties even though they are difficult to observe?
chemical properties
What was the first method of determining the chemical composition of substance in space?
I suppose that this method was alpha spectrometry.
What does not change when a substance changes matter?
During a physical change, the matter of what the substance is made out of doesn't change.
