Answer: Because new substances are formed.
Explanation: A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Once a chemical change occurs it cannot be undone due to the change in chemical identity. The creation of a new substance is not reversible.

Glucose falls under aldoses group of monosaccharides which are one of the carbohydrates.
<u>Explanation:</u>
Generally, a molecule formed by combination of carbon, hydrogen and oxygen are termed as carbohydrates. The smallest of the saccharides are mono and disaccharides. The saccharides can contain an aldehyde or a ketone group in their structural formula.
The molecular formula of glucose is C6H12O6. It falls under monosaccharide as the molecular formula of monosaccharides are (CH2nO)n where the n will be 3,5 or 6. So the molecular formula of glucose exactly matches with the molecular formula of monosaccharide family.
Also, it is known that glucose contains an aldehyde so it can be termed as aldose for being a carbohydrate in monosaccharide family containing aldehyde group.
The more electronegative an atom is, the more strength it has to pull electrons closer to itself. If one atom is highly electronegative and the other is barely electronegative then an ionic bond will form. If one is highly electronegative and the other is slightly electronegative, then a polar covalent bond will form. If they are both the same electronegativity then a nonpolar covalent bond will form.
