What are the similarities and differences between mixture and substance?
In chemistry:
- a pure substance consists only of one element or one compound.
- a mixture consists of two or more different substances, not chemically joined together.
What does a substance and mixture have in common?
Both pure substances and mixtures have properties like weight, color, volume, flammability, toxicity, etc. Similarly, a pure substance and a homogeneous mixture will have the same properties throughout the entire substance or mixture.
How are substances related to mixtures?
Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.
What is one similarity between a pure substance and a compound?
On first glance, elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances.
Which common substance is a mixture?
For example, tap water may contain small amounts of dissolved sodium chloride and compounds containing iron, calcium, and many other chemical substances. Pure distilled water is a substance, but seawater, since it contains ions and complex molecules, is a mixture.
What are the similarities of element and compound?
Can something be both a pure substance and a mixture?
Can something be both a mixture and a pure substance? Is it always possible to identify something as an element, compound, pure substance, or mixture just by looking at it? No because you cannot always see the chemical makeup of substances.
What do pure substance and solution have in common?
what does a pure substance and a solution have in common? A pure substance and a solution are common in that their compositions are uniform throughout.
What is the similarities of element?
How are pure substances and mixtures alike and different?
Mixtures and pure substances are alike because mixtures are made up of two or more pure substances. This means that where pure substances have a single set of properties, mixtures may have two or more sets of the same properties, based on the pure substances that make up the mixture.
What are the similarities of mixture and solution?
What are the similarities of mixture and solution? Mixtures that appear as if they are pure substances are called solutions. A solution like a mixture always have more than one kind of particle, but it appears as a pure substance. Solutions are often referred to as homogeneous mixtures.
How are oil and vinegar mixtures and pure substances alike?
Oil and vinegar form a heterogeneous mixture and any amount of oil can be mixed with any amount of vinegar. While this possible variation is a key feature of mixtures and distinguishes them from pure substances, the fact that mixtures are made up of pure substances remains the main basis for their similarities.
How is a homogeneous substance different from a pure substance?
A pure substance is a form of matter that has a fixed chemical composition and a distinct characteristic while a homogeneous mixture is a mixture of two or more compounds with compositions that are uniform or mixed together in such a way that they are indistinguishable from each other. Is gold alloy homogeneous or heterogeneous?
