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
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.
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 type of mixture is ice cubes in liquid water?
Ice cubes in liquid water is a heterogeneous mixture. An ice cube amy have bubbles in it and that would make it heterogeneous but often they are homogenweous. Ice is water a chemical compound. Here are the definitions of each: compound - a chemical combination of two or more different elements; can be broken down into simpler substances by chemical means and has properties different from those of its component elements (ex. water) heterogeneous mixture - one that does not have a uniform composition throughout and in which the individual substances remain distinct (ex. pizza) homogeneous mixture - one that has a uniform composition throughout and always has a single phase; also called a solution (ex. salt solution)
One difference between a compound and a mixture is a compound always?
A compound is composed of two or more elements chemically combined in a definite proportion. The components of a mixture are not chemically combined and can vary in proportion.
What is a material that always has a definite composition element compound mixture substance composition?
a substance
Is butter a mixture or a compound?
Butter is a mixture: Its atomic composition is not always constant from one source to another.

What is a substance with a constant composition?
No substance always has the same composition and properties, unless that substance is only considered in one of the various phases of matter. An element would be the logical choice, but many compounds and even solutions are the same no matter what (of course dependent on phase).
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.
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 a mixture always a mixture?
yes, a solution is always a mixture

Is ice water a compound element or mixture?
Ice is neither heterogeneous or homogeneous. It is actually a compound. Here are the definitions of each: compound - a chemical combination of two or more different elements; can be broken down into simpler substances by chemical means and has properties different from those of its component elements (ex. water) heterogeneous mixture - one that does not have a uniform composition throughout and in which the individual substances remain distinct (ex. pizza) homogeneous mixture - one that has a uniform composition throughout and always has a single phase; also called a solution (ex. soda)
What describes a heterogeneous mixture?
A heterogeneous mixture always contains more than one phase. A phase is a region with uniform composition and properties. The substances in a heterogeneous mixture remain physically separate e.g. sugar and sand.
