because it consists of only one type of molecule and physically sugar can not be separated into two or more components.
Glucose is a compound - C6H12O6; it cannot be broken down by physical means.
Sugar or perhaps table sugar is made of two different molecule boned together. These molecules are glucose and fructose. While the two molecules are isomers, they are two different molecules.
Sugar (table sugar or sucrose) is made of two different molecules, therefore not a pure substance.
Yogurt is not a pure substance because its a mixture of different elements/molecules (Cow milk and sugar and more...) from the Periodic Table
pure substance, propanone
Pureness is in the eye of the beholder. But monocrystaline minerals could be considered "pure" as could anything consisting of just one element or one compound.
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
Pure substances are made up of a single element, or a single compound. Table salt is a pure substance because it is made up of only the compound NaCl (sodium chloride). Diamond is a pure substance, it is made up of the element carbon. Air is not a pure substance, it is a mixture of several gaseous elements and compounds (nitrogen, oxygen, carbon dioxide..) Distilled water is a pure substance made up of a single compound H2O.
Yes. It is called sucrose and has a chemical formula of C12H22O11.
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.
Chocolate pudding would be considered a pure substance.
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
