Is all composition of a compound fixed but that of a mixture is not true or false?
False. The composition of a compound is fixed, meaning it always contains the same elements in the same proportions. In contrast, the composition of a mixture can vary, as it is a physical combination of substances that can be in different proportions.
Explain why the composition of an element is fixed.?
The composition of an element is fixed because each element is made up of a unique type of atom with a specific number of protons in its nucleus. This number of protons determines the element's identity, and any change in the number of protons would result in a different element. Therefore, the composition of an element cannot be altered without changing its identity.
Does a mixture obey the law of definite composition?
Yes, a mixture does not obey the law of definite composition. Mixtures can have varying proportions of different substances, whereas compounds, which obey the law of definite composition, have a fixed ratio of elements.
Does a compound have a chemical composition?
Yes
Does a compound have compositions that vary?
Yes, the composition of a compound is fixed and consistent, always containing the same ratio of elements. This is a fundamental characteristic of compounds and is defined by their chemical formula.
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.
What has a fixed composition and is always homogeneous?
A compound has a fixed composition and is always a homogeneous pure substance.
If the composition of a material is fixed?
If the composition of a material is fixed, it means that the material is made up of a set combination of elements in specific proportions. This fixed composition gives the material its unique properties and characteristics, which remain consistent as long as the composition is maintained.
Which is a property of a pure substance uniform composition fixed composition varying composition?
A property of a pure substance is fixed composition. This means that the substance is made up of only one type of molecule or atom throughout, with no variation in its chemical composition.
Does mixtures have a composition?
Mixtures don't necessarily have fixed composition
Do colloids have a fixed composition?
No, the composition is variable - excepting of course specific recipes.
What type of matter has fixed composition?
A substance
What same fixed composition and properties is known as a?
substance
Is water mineral salts?
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
Is salt water a mineral?
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
Is all composition of a compound fixed but that of a mixture is not true or false?
False. The composition of a compound is fixed, meaning it always contains the same elements in the same proportions. In contrast, the composition of a mixture can vary, as it is a physical combination of substances that can be in different proportions.
A mineral is a what because it has a fixed composition?
This information is correct but not totally; frequently some differences in composition exist.
