Why is pencil insoluble?
The pencil lead is not lead but is made from soft graphite carbon and insoluble except as carbon tetra chloride
Does pencil lead contain carbon?
yes
Will you get lead poisoning if graphite from a pencil enters the bloodstream?
No ,because there is no lead in a graphite pencil, only carbon.
What do coal pencil lead and diamonds have in common?
Coal, pencil lead, and diamonds all contain carbon.
Why is carbon used in a pencil?
Because lead used to be used, and that was poisonous to humans, graphite is actually the name of what's used now.
Does a pencil conduct electricity?
Yes the center carbon or lead can conduct electricity. The carbon in the pencil is also used in resistors for resistance in a circuit.
Why can pencil lead can be used to make a light bulb?
A "pencil lead" is a mixture of the graphite allotrope of carbon mixed with clay and baked hard. While a pencil lead will conduct electricity, it can not be used to make a light bulb.
What element element is in the carbon family often mistaken for the end of your pencil?
Pencils use Graphite, not lead. Graphite is made of carbon, and no one mistakes a pencil of having carbon. They may mistake it of having lead, in which it is corrected that pencils no longer use lead-but instead use Graphite, which is made of carbon. It is not often mistaken that a pencil is made of carbon. Because it is made of carbon, so how you can make a mistake by thinking the pencil is made of graphite? Its true, not a mistake. This riddle is probably backwards? Or its just a trick question, I dont even know.

Is a pencil a example of a wheel and axle?
No, a pencil is an object used to apply carbon lead to writing materials.
Is lead not as in pencil lead magnetic?
Lead is not magnetic. Pencil lead is really carbon, in the form of graphite, and it is not magnetic.
Is pencil lead magnetic?
No. Also, "pencil lead" is not lead; it is almost always graphite (made of carbon)
What is the driffrent numbers on the side of the pencils for?
The number of the pencil is based on the type of carbon lead used inside. The thicker the carbon lead gets the higher the number of the pencil becomes. If you notice a mechanical pencil is 0.9mm in diameter so it would be called a #0.9 pencil. A #2 pencil's lead is 2mm in diameter. So Why would we call a pencil a #3 pencil? Because it's lead is 3mm in diameter.
Which has the most lead aluminum or pencil lead?
Pencil lead isn't really lead, it is graphite, a form of carbon. Pencil lead doesn't have any lead in it whatsoever.
Is there carbon in lead?
no.perhaps you are thinking of pencil lead, which isn't lead. its carbon in form of graphite.
What mineral when mixed with clay is used to make pencil lead?
Graphite, a form of carbon
Is pencil magnetic?
No. Also, "pencil lead" is not lead; it is almost always graphite (made of carbon)
