Graphite exists as: a) Two dimensional layers of covalently bonded carbon atoms
b) A linear chain of covalently bonded carbon atoms
c) A tetrahedral structure of covalently bonded carbon atoms
d) A linear chain of covalently bonded carbon and hydrogen atoms

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
