Can compounds be physically separated into their original substances?
Yes, compounds can be physically separated into their original substances through physical methods such as distillation, filtration, or chromatography. These methods work based on the differences in physical properties of the components of the compound.
How do you calculate the percent composition of an original mixture?
To calculate the percent composition of an original mixture, you first determine the mass of each component in the mixture. Then, you calculate the total mass of the mixture by summing the masses of all components. Finally, the percent composition of each component is found by dividing the mass of each component by the total mass of the mixture, and then multiplying by 100 to express it as a percentage.
What is the Measure of the tendency of a chemical compound to maintain its original chemical composition?
Chemical stability is the measure of a chemical compound's tendency to maintain its original chemical composition under specific conditions. It indicates how likely a compound is to undergo reactions or decompose over time.
Why converting wood to saw dust is considered to be an irreversible change?
Converting wood to sawdust involves physically breaking down the structure of the wood into smaller particles. This change is irreversible because the original composition of the wood is permanently altered when it is reduced to sawdust, making it difficult to revert back to its original form without significant effort or energy input.
How do you rewritten formal composition expel?
To rewrite a formal composition, begin by carefully analyzing the original text to understand its main ideas and structure. Then, rephrase sentences while maintaining the original meaning, using varied vocabulary and sentence structures to enhance clarity and flow.

He had named many of the streets after English Statesmen and it is thought that he named Kew for its counterpart in London due to its proximity to Richmond.
If two chemicals are mixed together is it a physical change?
No, mixing two chemicals together is a physical change because the substances retain their original chemical properties. The chemical composition remains the same even though they are physically combined.
Would you get the same fragrance by burning something as by melting it?
No. By burning something you are breaking it down and forming new products (smoke, carbon dioxide, etc), and these are different from the original compound. In contrast, when you melt something, some of it is actually vaporized at the same time, and that is what you are smelling. So when you melt it, you smell the molecules of the original compound, whereas when you burn it, you are smelling the compounds that were formed during the burning process. That said, when burning something, you will probably also smell some of the original compound, because usually when something is burning, some of it is also vaporized and not all of it is burned.
Is hot coffee a homogeneous or heterogeneous mixture?
Coffee is a homogeneous mixture (assuming it has been well-stirred), as the mixture has a uniform composition throughout. Dividing the mixture into macroscopic parts, each part will have the same composition as the original mixture.
