What is the difference between homogeneous and heterogenous mixtures?
A heterogeneous mixture is one that does not blend smoothly and in which the individual substances remain distinct. A homogeneous mixture has the same composition throughout, and always has a single phase. A heterogeneous mixture's components are not evenly distributed and are immiscible, or not able to be mixed. A homogeneous mixture's components are evenly distributed and are miscible, or able to be mixed
What is a fixed mixture?
A fixed mixture is a combination of substances that always maintains the same composition and properties throughout. The components of a fixed mixture are evenly distributed and cannot be separated by physical means like filtration or distillation. Examples include alloys like bronze and solutions like salt water.
Is a mixture always a chemical combining of substances?
Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
Is the proportion of iron and sulphur in a mixture always fixed?
No, the proportion of iron and sulfur in a mixture is not always fixed. It depends on the specific composition of the mixture and how it was prepared. Different mixtures can have varying ratios of iron and sulfur based on their intended use or source.
What is shales chemical symbol?
It doesn't have one. Shale is a mixture and doesn't always have the same composition. Only elements have chemical symbols
What is a material that always has a definite composition element compound mixture substance composition?
a substance

Is the proportion of iron and sulfur in a mixture is always fixed?
No, the proportion of iron and sulfur in a mixture is not always fixed. It can vary depending on the composition of the mixture and how it was prepared. The proportion can be adjusted by changing the quantities of iron and sulfur added to the mixture.

Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
Why is air a homogenous mixture?
Air is a homogeneous mixture because it is made up of different gases (such as nitrogen, oxygen, and carbon dioxide) that are uniformly distributed throughout the atmosphere. This means that the composition of air is consistent throughout, regardless of where it is sampled from.
Is the proportion of iron and sulphur in a mixture always fixed?
No, the proportion of iron and sulfur in a mixture is not always fixed. It depends on the specific composition of the mixture and how it was prepared. Different mixtures can have varying ratios of iron and sulfur based on their intended use or source.
What is a single kind of matter that is pure meaning it always has a specific makeup or composition to it?
An element, as opposed to a compound or mixture.
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.
What is shales chemical symbol?
It doesn't have one. Shale is a mixture and doesn't always have the same composition. Only elements have chemical symbols
Is butter a mixture or a compound?
Butter is a mixture: Its atomic composition is not always constant from one source to another.
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.
