Compounds can be decomposed by chemical reactions.
In compounds, particles are chemically bonded together to form a new substance with its own unique properties, whereas in mixtures, particles are not chemically bonded and can be easily separated by physical means. Compounds have a fixed ratio of atoms, while mixtures can vary in composition.
A heterogeneous mixture is one where the components are visibly different and can be easily separated using physical methods like filtration or sorting. Examples include a mixture of sand and salt, where the sand particles can be seen and separated from the smaller salt particles.
no ---------- Elements are atoms, which can be separated into smaller particles such as protons, neutrons, electrons, and quarks, but usually not by chemical processes.
Yes they can be easily separated.
A solution, such as saltwater, cannot be separated by filtration because the solute (salt) is dissolved at the molecular level in the solvent (water). Filtration works by trapping larger particles while allowing smaller particles or dissolved substances to pass through, so dissolved substances remain in the solution. In contrast, substances like sand or gravel can be separated by filtration because they are solid particles that do not dissolve in the liquid.
physical
Compounds can be separated into their elements through chemical reactions, such as electrolysis or thermal decomposition. Additionally, compounds can be separated by physical methods such as distillation, filtration, or chromatography. Each method relies on the differences in physical or chemical properties of the elements in the compound to achieve separation.
Elements are pure substances consisting of only one type of atom, meaning all their particles are identical. Compounds are formed when two or more different types of atoms chemically bond together, resulting in particles that are made up of these combined atoms. Mixtures, on the other hand, consist of two or more substances (elements or compounds) that are physically combined, where the individual particles retain their own properties and can be separated by physical means. Thus, the key difference lies in the uniformity and bonding of the particles involved.
Sometimes is possible, depending on the type of the coloid; for example aerosols.
what do you mean
Compounds can be separated into their constituent elements only by a decomposition reaction.
Mixtures can be separated by physical methods.
