Sugar is a pure substance because it has a definite composition. Its molecular formula is C12H22O11.
yes,water, sugar, gold, ect are all pure substances

The pure substances from the options provided are a rod of steel, a cube of sugar, and a block of wood. Steel and sugar are pure chemical compounds, while wood is a homogeneous mixture of different compounds but is considered a pure substance in the context of the question. Leather and milk are mixtures of various compounds and are not pure substances.
it is not true it is a chemical reaction
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.
None of these are pure substances. All are mixtures.

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.
