Yes. It is called sucrose and has a chemical formula of C12H22O11.
Yes, a cube of sugar is considered a pure substance. It is a pure substance because it only contains a single molecule of sucrose.
Yes, sugar is a pure substance because pure substances are either compounds or elements. In this case it is a compound.
Yes. Because it is a crystal.
It is pure if this sugar is not mixed with another substance.
If it's without milk or sugar - it's a pure substance.
Dextrose is a pure substance.
Sugar is a compound, a pure substance, as it only contains sucrose.
That would depend on how you define "change" and "sugar cube". If moving a sugar cube changes it, since you could move any sugar cube to an uncountable number of other locations, such a sugar cube could change in an infinite number of ways. If you define "sugar cube" as a six sided solid of glucose, you could substitute any one or more of several billion atoms for its isotope, and change it into a different sugar cube. If you allow chemical reactions, as in "how many ways can the contents of a sugar cube be used to make another substance?", then again, there are an infinite number if potential transformations. If you were to hurl a particular sugar cube into the ocean or the sun, in a thousand years, atoms from that cube would be found in several billion organisms.

Pure sugar is a substance (compound).
It is pure if this sugar is not mixed with another substance.
Refined substance can be a pure substance depending on the type of sugar used. If the refined sugar is white, then it is a pure substance. If it the refined sugar is brown, then it is not a pure substance.
Yes, sugar (sucrose, C12H22O11) is a compound, with only one type of molecule, which is a pure substance.
There are many types of sugar but, if you are describing one type of sugar and not a mixture of many sugars it would be a pure substance.
Sugar is a pure substance because everything in a sample is alike: a molecule of sugar.
A sugar is a pure substance. Sugar is the generic name for many compounds which are all pure substances. Fructose is a sugar. Glucose is a sugar. Lactose is a sugar. Glucose + Fructose --> Sucrose This is a chemical reaction between 2 sugars to make another, more complex sugar. This reaction if I remember correctly eliminates a water molecule as well as producing sucrose. The reaction occurs in certain plants and is done by an enzyme. Mixing fructose and glucose in a bowl will NOT form sucrose. Refer to the wikipedia article on sugar. It shows the molecular structure of sucrose. A substance cannot have a molecular structure if it is a mixture. It is a compound and compounds are pure substances.
If it's without milk or sugar - it's a pure substance.
Pure sugar is a compound, which is a pure substance. If you dissolve sugar in water, you will have a homogeneous mixture, which is a solution.
Pure substance can be identified as either elements or compounds. Some examples of pure substance that are elements are sulfur and tin. Pure substances that are compounds are sugar and salt.
