a pencil "lead" is actually made of graphite. graphite is made exclusively of carbon atoms. which two terms best describes graphite? A. compound. B. mixture. C. pure substance. D. element

A & C.

Explanation:

cannot be an element, element = C (carbon), not graphite.

cannot be a mixture: graphite is only made out of carbon atoms.

It is a pure substance and a compound.

The answer is C, as it states it's made of ONLY carbon atoms, not any others.

The answer is also A, because Graphite is still considered a compound.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

its c i just checked it
