What is the term for matter having indefinite composition and variable properties?
The term for matter having indefinite composition and variable properties is a mixture. Mixtures can be homogeneous (uniform composition) or heterogeneous (non-uniform composition).
When all samples of a material have identical properties and composition it is?
Element
Is 14-k gold homogeneous or heterogeneous?
14-karat gold is considered homogeneous because it is a single phase alloy, with a uniform composition throughout the material.
Is an 18k gold ring homogeneous?
Yes, an 18k gold ring is homogeneous in terms of its composition. It is made of 75% gold and other alloy metals, such as silver or copper, to provide strength and durability. The entire ring is consistent in its material composition, making it homogeneous.
Is bronze a homogeneous or heterogeneous mixture?
Bronze is considered a homogeneous mixture because it is a uniform alloy composed of copper and tin atoms dispersed throughout the material. This results in consistent properties and composition throughout the material.

Is a silver ring homogeneous or heterogeneous?
Yes, it is a homogeneous metal.
Is magnalium homogeneous?
Yes, magnalium is considered a homogeneous material because it is a solid solution of magnesium and aluminium. This means that the composition of magnalium is uniform and consistent throughout its structure, giving it homogeneous properties.
Is an 18k gold ring homogeneous?

Is bronze a homogeneous or heterogeneous mixture?
Bronze is considered a homogeneous mixture because it is a uniform alloy composed of copper and tin atoms dispersed throughout the material. This results in consistent properties and composition throughout the material.
Is sodium nitrate homogeneous?
Yes, sodium nitrate is a homogeneous substance. It is a compound formed by the combination of sodium ions and nitrate ions, resulting in a uniform composition throughout the material.
What has a fixed composition and is always homogeneous?
A compound has a fixed composition and is always a homogeneous pure substance.
Is pennies and dimes homogeneous?
The coins are of homogeneous composition.
Is 18k gold homogeneous or heterogeneous?
18k gold is homogeneous because it is a substitutional solid solution of gold and other metals like copper or silver. The composition of the metals is uniform throughout the material, making it a single phase.
What is variable composition?
I am not 100% sure, but i believe variable composition is when the composition of a mixture can vary, or contain different properties, elements/compounds... etc. An example of variable composition would be a heterogeneous mixture, which has no uniform way of being composed. Where as its opposite, a homogeneous mixture, has a set composition of the same properties, elements/compounds... etc. and can be recreated.
