Answer #1
In chemistry, there are two types of combinations that may occur when substances of different types are put together, one is called a compound and the other is known as a mixture. They are also used to classify matter accordingly together with element.
Compound and mixture are different from each other in many aspects that includes how the involved substances are combined, presence and absence of chemical reaction and of energy, the characteristics of its structure, the capacity of the combined elements to be separated and turned back into its original forms, and the condition whether the combined substances can still be recognized or not.
In compound, the combination of substances involves a chemical reaction. The molecular composition of the matter reacts chemically and creates a bond between the atomic structures of the affected substances. In mixture, the reaction between combined substances is merely physical in nature.
Since the reaction associated with a compound is in a chemical form, the change is also chemical and that an amount of energy (light, heat, and so forth) is either absorbed or released during its formation. However in mixture, there is no presence of chemical change. And in normal conditions, mixture does not involve any use or loss of energy during formation.
The chemical structure of a compound is definite, fixed, and relative to mass. The structure of a mixture can be present in any degree and in variations.
In addition to these, a compound does not usually bear a resemblance to the original component from which it was derived. The individual property of the components included in a compound loses its state and results to new properties as a compounded substance. A mixture’s components retained its properties and characteristics by which it can be easily identified even by sight. In relation to this, the elements within a compound are hard to separate, possible through a chemical reaction but is usually difficult to attain. A mixture’s elements nonetheless can be easily separated even without much effort.
