The particles that combined in the middle of the structure best describes neutron as neutron is always present in the middle of atomic structure
The main points of Dalton's atomic theory are: Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass.
Answer: A)There is a high ratio of energy to cost
Positives:
A Chunk of Uranium can power a city a lot longer than a chunk of coal.
It also does not contribute to pollution since what comes out of the tower is steam.
Negatives:
It is very expensive to build and maintain a nuclear power plant at first so investors whom want money up front are more reluctant to loan money for one.
If the plant does melt down it is very bad for the enviroment and its people, for example Chernobyl Nuclear Power Plant in the Ukraine will not be able to be lived in for approximently 20,000 years.
Answer:
47911.1 pa
Explanation:
The SI base unit of pressure is pascal, which is N/m^2.
2200 kg is 2200*9.8=21560 N, and 4500 cm^2=4500/10000=0.45 m^2.
So the total pressure exerted on the ground (!!) is 21560/0.45= 47911.1 Pa.
A single-displacement reaction, also known as asingle-replacement reaction, is a type of chemicalreaction<span> where an element reacts with a compound and takes the place of another element in that compound. This type of </span>reaction<span> is typically pictured like this: Here, A replaces B in the compound BC.</span>
