What are materials that are made up of pure elements of compounds in varying proportions called?
Materials that are made up of pure elements or compounds in varying proportions are called mixtures. Mixtures can be homogeneous (uniform composition throughout) or heterogeneous (non-uniform composition). Examples include solutions, suspensions, and alloys.
What is the difference between a mixture and a solution, and how do their properties vary in terms of composition and uniformity?
A mixture is a combination of different substances that are not chemically bonded together, while a solution is a type of mixture where one substance dissolves in another. Mixtures can have varying compositions and may not be uniform throughout, while solutions have a consistent composition and are uniform in their properties.
What makes a pure substance a pure substance?
A pure substance is made up of only one type of atom or molecule, meaning it has a consistent and uniform composition throughout. This distinguishes it from mixtures, which contain varying proportions of different substances. Examples of pure substances include elements like gold and compounds like water.
Is a rotten banana a homogeneous mixture?
No, a rotten banana is not a homogeneous mixture. A homogeneous mixture has uniform composition and properties throughout, whereas a rotten banana is a heterogeneous mixture with varying degrees of decomposition in different parts of the fruit.
How can you classify mixture?
Mixtures can be classified as homogeneous or heterogeneous. Homogeneous mixtures have uniform composition and properties throughout, while heterogeneous mixtures have distinct phases with varying properties. Mixtures can also be classified based on particle size as solutions, suspensions, or colloids.
Is pure substance uniform composition?
Yes, a pure substance has a uniform and definite composition. It is made up of only one type of element or compound, with consistent proportions of its constituent particles. This uniformity distinguishes pure substances from mixtures, which can contain multiple substances in varying proportions.

What must be true when two substance form a mixture Apex?
When two substances form a mixture, they must retain their individual properties and identities, meaning they do not undergo a chemical change. The components can be present in varying proportions and can typically be separated by physical means, such as filtration or distillation. Additionally, the mixture can be homogeneous (uniform composition) or heterogeneous (distinct layers or phases).
Is low density a metal?
Low Density a Metal?NO!!!!
Do compounds have varying compositions?
No. A compound will always have the same composition.
Is a rotten banana a homogeneous mixture?
No, a rotten banana is not a homogeneous mixture. A homogeneous mixture has uniform composition and properties throughout, whereas a rotten banana is a heterogeneous mixture with varying degrees of decomposition in different parts of the fruit.
How are pure substances like mixtures?
Pure substances are different from mixtures in that they have a fixed composition and uniform chemical properties throughout. In contrast, mixtures are combinations of two or more substances that can vary in composition and may have varying properties at different parts of the mixture.
How can you classify mixture?
Mixtures can be classified as homogeneous or heterogeneous. Homogeneous mixtures have uniform composition and properties throughout, while heterogeneous mixtures have distinct phases with varying properties. Mixtures can also be classified based on particle size as solutions, suspensions, or colloids.
What is the difference between substance and a pure substance?
A pure substance is one which contains only that substance and nothing else. An impure substance contains other substances in varying amounts.
What is the difference between mixture and pure substance?
Pure substances have uniform distribution of particles and can be either an element or compound. Mixtures can be separated easily and are not chemically bonded. They do not have uniform distribution.
