True. For example, electron domain geometry and molecular geometry of water and ammonia are different.
Answer:Mechanical weathering
weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
<span>The answer is hypertonic. In osmosis, water
molecules move from a hypotonic solution to the hypertonic solution, through a
semipermeable membrane. This occurs until
both solutions become isotonic relative to each other. In osmosis, only
the movement of water molecules occurs since the ions are large enough to pass
through the pores of the semipermeable membrane,
in this case, the cell membrane. Due to
loss of water in the process of osmosis, the cells in the fingers of the swimmers
shrunk hence looked shriveled.</span>
Answer:
Each carbon atom is covalently bonded to 4 other carbon atoms in diamond. A large amount of energy is required to split these atoms apart. This is because of the fact that covalent bonds are strong.
Blocks of magnesium is used to prevent iron corrosion.
This way of prevention is called sacrificial protection.
