132 g of C , 22 g of H , 176 g of O
132 + 22 + 176 => 330 g <span>of the substance
</span>Now convert the masses in <span>moles :
</span>
C = 12.0 u H = 1.0 u O = 16.0 u
C = 132 / 12.0 => 11 moles
H = 22 / 1.0 => 22 moles
O = 176 / 16.0 => 11 moles
Using the values obtained the lowest proportion in mols of elements present, simply divide the values found for the least of them<span>:
</span>
C = 11 / 11 => 1
H = 22 / 11 => 2
O = 11 / 11 => 1
formula empirically <span>is : CH</span>₂O
hope this helps!
Answer:
Chain reaction
Explanation:
A chain reaction is a process by which neutrons that have been released in a first nuclear fission produce an additional fission in at least one more nucleus. This atomic nucleus fishes and releases more neutrons, giving the opportunity to repeat the process.
Nuclear fission is the physical-chemical reaction through which the nucleus of an atom is split. In the main interest of fission reactions is that through this operation a large amount of energy is obtained. According to the definition of nuclear energy, atomic energy is the energy contained in the nucleus of an atom and the energy obtained is thermal energy, energy in the form of heat.
The other form of exploitation is through nuclear fusion reactions. In this case, the process is reverse, merging two different nuclei forming a single atomic nucleus.
After fission of the atomic nucleus we obtain various fragments with a mass almost equal to half of the original mass plus two or three neutrons. It is remarkable the release of these two or three neutrons because they are what will allow a new reaction in another atom.
Answer:
The half-life of Material 1 and Material 2 are equal.
Explanation:
Material 1 disintegrates to half its mass three times in 21.6 s, to go from 100g
to 12.5g. That is,
100g - 50g - 25g - 12.5g
Material 2 disintegrates to half its mass three times in 21.6 s, to go from 200g to 25g. That is,
200g - 50g - 25g - 12.5g.
This means that regardless of their initial masses involved, material 1 and material 2 have equal half-life.
Their half-life is 21.6 ÷ 3 = 7.2 sec
