Things that can be separated by physical means are mixtures. There are two types of mixtures: homogeneous and heterogeneous. In a heterogeneous mixture, you can see the different components that make up the mixture. You can't see the components in a homogeneous mixture. Things that can only be separated by chemical means are compounds.

Why are a substance's physical properties a reliable means to identify it?
A substance's physical properties, such as color, density, melting point, and solubility, are determined by the arrangement of its atoms and molecules. These properties are unique to each substance and do not change regardless of the amount or form of the substance present. Therefore, by comparing the physical properties of an unknown substance to those of known substances, we can reliably identify it.
What is a substance that can be be separated by physical means?
It wouldn't be a single substance, it would be a mixture.
What is a substance mixed with simpler substances by chemical means?
physical means only
Is matter a pure substance?
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.
What are the characteristics of substance and mixtures?
Mixtures: can be separated by physical means
What the characteristics of substance and mixture?
Mixtures: can be separated by physical means
What are the signs of a physical changes?
A physical change to a substance is a change in its state. This means that the substance goes from a solid to a liquid or gas, or vice versa.
What does a substance mean?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
Is ripening mango is physical change?
yes it is a physical change because physical change means change in which no new substance is formed. so when a mango is ripen there is no new substance formed thus it is a physical change
When two or more substance are combined so each substance can be separated by physical means the result is an?
The result is an MIXTURE
Deoxy means to remove the substance known as?
Oxygen.
What property describes the ability of a substance by physical or chemical means?
The property that describes the ability of a substance to undergo changes through physical or chemical means is known as reactivity. Reactivity refers to how readily a substance combines with others to form new substances, which can involve chemical reactions. Physical properties, on the other hand, pertain to characteristics that can be observed without changing the substance's chemical identity, such as color, melting point, and density. Together, these properties help define how substances interact and transform in various conditions.
