Lead is a chemical element, not a mixture.
Lead metal is a homogeneous mixture because it is composed of only one type of element, lead, with uniform properties throughout.
Homogeneous and heterogeneous can apply to a range of things, one example would be to catalysts.
heterogeneous
Lead is a chemical element not a mixture.
A pewter mug is homogeneous because you cant see the different substances that make it. If you want to think of different terms, if you take the mug and the handle of it, they are 2 separate things which can also make it heterogeneous. honestly, both terms work!
A homogeneous mixture is a mixture where the components are evenly distributed and the composition is uniform throughout. This means that you can't distinguish between the different substances in the mixture.
Yes, pencil lead is homogeneous because it is a mixture of graphite and clay that is uniform in composition throughout. This uniformity allows the pencil lead to have consistent writing properties.
heterogeneous No, it is HOMOGENEOUS. (edited by Dr. J.)
Lead is a chemical element not a mixture.
sugar itself is not a mixture, now dissolved in water is homogeneous, increasing quantity can lead to hetergeneous mixture because of precipitate
It is a pure substance.
Heterogeneous
A pewter mug is homogeneous because you cant see the different substances that make it. If you want to think of different terms, if you take the mug and the handle of it, they are 2 separate things which can also make it heterogeneous. honestly, both terms work!
Lead is a pure substance, not a mixture. It is an element with the chemical symbol Pb, and it consists of only one type of atom.
A river is heterogeneous, because it has several different substances, such as broadly silt and fish (if you're thinking about it like that) or it is also contained, H20, O2, substances like that so either way it is heterogeneous.
A homogeneous mixture is a mixture where the components are evenly distributed and the composition is uniform throughout. This means that you can't distinguish between the different substances in the mixture.
Pewter is a mixture because it is made up of multiple elements, such as tin and other metals like copper and antimony, that are physically combined but do not chemically bond together.
heterogeneous No, it is HOMOGENEOUS. (edited by Dr. J.)
A pencil is a tool made of a compound material, typically consisting of graphite mixed with clay and other materials.
Pencil lead is actually not lead (Pb) at all, but it is graphite. And graphite is simply carbons atoms. So, no, it is NOT a compound mixture.
