Does the composition of a substance always stay the same?
The composition of pure substances, such as elements and compounds, are always the same. The composition of mixtures can vary.
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.
The composition of a mixture can vary unlike a compound?
Yes, Mixtures can vary but the composition of a compound cannot
The composition of a mixture can vary unlike a compound explain why?
Compounds are made by combining two elements to an exact percentage, to change one thing would revert it to its original elements. Mixtures are combinations of two elements that do not depend on this as a mixture is not chemically bound. Jay Sanga
What you mean by composition?
For substances, composition means the constituent materials or elements. For writing or music, composition is the act of composing or creating, combining the separate elements or aspects into a whole.
What is matter that can vary in composition?
a mixture
Can the composition vary in a homogeneous and heterogeneous mixture?
No. The composition of a homogeneous mixture, called a solution, can vary.
What is a elemental composition?
This is the composition of a chemical compound expressed in contained chemical elements.
How are the properties of a compound different from those in a mixture?
A compound has a definite composition, while a mixture's composition can vary.
What are the two elements for a candle?
The two components of a candle are wax and a wick. The elemental composition of both components can vary greatly. I'm going to take this literaly. Wax + wick
Are all the stars the same?
No. Stars vary in mass, color, size, temperature, and composition of trace elements.
Is fixed composition a caracteritic of a mixture?
A fixed composition is not a characteristic of a mixture. The composition of a mixture can vary, unlike the composition of a compound that forms a chemical reaction.
