8.11C Human Dependence on Ocean Systems Artificial reefs, such as old ships placed in the ocean by humans, affect the ecosystems of
the ocean. How can these artificial reefs change the ecosystem?
A. Artificial reefs provide less protection to small fish.
B. Artificial reefs provide a new habitat for organisms.
C. Artificial reefs provide more oxygen to organisms.
D. Artificial reefs provide additional locations to drill for
oil.

As a part of an experiment a student burns propane to produce carbon dioxide and water she remembers that she must follow the law conservation of matter when writing a balanced chemical equation which of these equation adheres to the law of conservation of matter

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
