Compound and mixture are both types of combinations, but they have different characteristics and outcomes.
A compound is formed when two or more elements chemically react with each other and combine to form a new substance with different properties. The chemical bonds between the atoms of the elements are rearranged to create a compound with a specific chemical formula. Compounds have a fixed composition and their properties differ from those of the elements that make them up. For example, water (H2O) is a compound formed by the chemical reaction of hydrogen (H) and oxygen (O) atoms.
On the other hand, a mixture is formed when two or more substances are physically combined, without any chemical reaction taking place. The substances in a mixture retain their original properties and can be separated through physical means, such as filtration or distillation. Mixtures do not have a fixed composition and can be in any proportion. For example, a mixture of salt and sugar can be easily separated by dissolving them in water and then evaporating the water to obtain the separated components.
In summary, compounds are formed by the chemical combination of elements, resulting in a new substance with different properties, while mixtures are formed by the physical combination of substances, retaining their individual properties.
