Answer:
GRAPHENE is a single layer of graphite
Explanation:
each carbon atom bonded to 3 other carbon atoms forming a hexagonal lattice
I believe they are converted to energy
D
Molecular motion increases as temperature increases and therefore increasing the molecular motion increases collision frequency.
Explanation:
When a substance is heated, its molecules gain increased kinetic energy even as the substance increases in temperatures. With higher kinetic energy, this means the molecules are moving more rapidly and hence collision between the molecules will be more frequent and of higher energy. It is these high energy collisions that cause the molecules to move further away from each other with increased temperatures (why substances expand).

Answer:
B. C, A, B
Explanation:
We can measure the age of an artifact by comparison of the activities a living sample with that of the artifact. This is so because the activity of the living sample represents the original activity of the artifact.
So, the steps involved in determining the age of an artifact is to measure the ratio of the parent and daughter nuclei. Then we use the half life of carbon to find out how many half lives have passed. Using this number of half lives that has passed, we can compute the age of the object.
