Blood is made up of several different substances, whereas graphite occurs naturally in the form of graphite.
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.
The "lead" is a mixture of GRAPHITE and CLAY. It is squirted out like spaghetti and baked hard.
Pencil lead is a mixture of graphite (or other colored pigment) and a binder (e.g. clay, wax, plastic, grease).
No, graphite and diamond are not elements. They are both forms of the element carbon. Carbon is the element, while graphite and diamond are allotropes, which are different forms of the same element with different physical and chemical properties.
Graphene is not likely to be put on the periodic table as it is a single layer of carbon arranged in a 2D structure. The periodic table typically includes elements, not specific structures or materials derived from those elements.
Graphite is an element. It is composed entirely of carbon atoms arranged in a specific crystalline structure.
No, graphite is a pure substance. It is a form of the pure element carbon.
No. Graphite is a pure element, it is an allotrope of Carbon.The allotropes of the element Carbon are :- diamond, graphite, graphene, amorphous carbon and buckminsterfullerenes.
Graphite is a pure substance and a crystalline form of carbon. It is not a mixture since it is composed of only one type of atom, carbon. Additionally, graphite is not a metallic element, it is a non-metal.

Blood is a Mixture.
Blood is a mixture containing plasma and blood cells.
The black stuff in the middle of the pencil is a mixture of graphite (an element that is mined) and clay.
Graphite is made of carbon and only carbon. Blood is composed of water, proteins, ions, and cells. Since there is more than one type of atom, it is not an element. Since there is more than one type of particle, it is not a compound. This makes it a mixture. Since the composition of the mixture doesn't differ significantly between different samples from the same organism on the same day at the same time, it can be called a homogeneous mixture.
