Answer:
The answer to your question is: Volume = 29.79 cm³
Explanation:
Data
Density of gold = 19.3 g/cm3
Mass = 575 grams
Formula
density = mass / volume
Volume = mass/density
Volume = 575 g / 19.3 g/cm3
Volume = 29.79 cm³

Answer:
Explanation:
For example, the energy released in burning 1 mol of octane, a component of gasoline, is about 5000 kJ.
The energy released in the fission of 1 mol of uranium-235 is
about 1.5 × 10¹⁰ kJ
.
The ratio is
Answer:
5.81L
Explanation:
N1 = 1.70 moles
V1 = 3.80L
V2 = ?
N2 = 2.60 moles
Mole - volume relationship,
N1 / V1 = N2 / V2
V2 = (N2 × V1) / N1
V2 = (2.60 × 3.80) / 1.70
V2 = 9.88 / 1.70
V2 = 5.81 L
The volume of the gas is 5.81L
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.
