a glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate.
Formation of ethyl glucoside : Glucose and ethanol combine to form ethyl glucoside and water. The reaction often favors formation of the α glycosidic bond as shown due to the anomeric effect.
A glycosidic bond is formed between the hemiacetal or hemiketal group of a saccharide (or a molecule derived from a saccharide) and the hydroxyl group of some compound such as an alcohol. A substance containing a glycosidic bond is a glycoside.
Answer:
the energy of matter implies the motion of masses and the energy of the wave has no moving masses
The energy of the particles (matter) is the ability to do some work, therefore the energy can be of motion in the form of kinetic energy or in a configuration of the system called potential energy, the sum of these two energy is constant .
The wave is formed by a disturbance of the medium by matter, therefore for the formation of the wave matter supply energy, for example: in the form of movement, in the form of fluctuation of electric or magnetic field, etc.
The waves after being formed can move away from the matter that formed them, transporting the energy that alternately has kinetic and potential energy, but the total energy is constant.
Therefore the energy in matter is due to the movement of the same and the energy in the wave does not require the movement of matter, so it is a more efficient way of doing work.
In conclusion, the energy of matter implies the movement of masses and the energy of the wave has no moving masses.
<span>Answer: a mixture.
</span><span>Justification:</span>
<span /><span>
</span><span>1) Pure substances have a definite chemical formula: the same kind of atoms with the same fixed ratios and chemical bonds. Therefore, the percents of each element do not varye.

2) Elements and compounds are pure substaces. For example, Fe, Mg, Ti, are elements, and CO₂, CO, H₂CO₃ are compounds. Each of them will have always the same kind of atoms, in the same ratio and with the same chemcial bonds. Therefore the percents of the elements do not varye.
</span><span />
<span>3) Mixtures are formed by the physical combination (not chemical bonds) of different elements or compounds in variable proportions. As indicated, this describes the material bronze, in virtue of the variation of its composition. Other examples of mixtures are solutions (like brines), air, ocean water, and milk: different brines, different oceans and different milk have different contents of elements or compounds.
