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.
No, a pencil is not poisonous. However, ingesting pencil lead or graphite can lead to an intestinal blockage or irritation.
A 7mm pencil lead is thicker than a 5mm pencil lead. The diameter of the lead determines its thickness, so the lead with a larger diameter will be thicker.
Graphite is the mineral that is used to make the lead in a pencil. Despite its name, pencil "lead" is actually composed of graphite mixed with clay.
The streak color of pencil lead is typically a shade of grey.
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.
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
Yes, pencil "lead" is not actually lead metal but graphite, which is a form of carbon. So, pencil lead is Pb (lead) free.
Pencil lead is a compound
It's not a 'solution' but if you consider it that way then the answer is no. Homogeneous means 'the same throughout'
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
No, a pencil is not poisonous. However, ingesting pencil lead or graphite can lead to an intestinal blockage or irritation.
we get lead of pencil from the mixture of clay and graphite
Pencil lead is a conductor.
A 9mm pencil lead is thicker than a 7mm pencil lead.
Pencil lead is made of graphite and clay. Newer recipes for pencil lead use waxy polymers to bind the graphite to produce a lead that does not snap when the pencil is flexed.
It is called a lead pencil. Despite the name, the "lead" in pencils is actually made of graphite, not lead. Lead pens are typically mechanical pencils that use a lead refill.
