Answer:
The figure here is missing, so we cannot say what is the corresponding letter; however we can describe what nuclear fusion is.
Nuclear fusion is a nuclear process in which light nuclei fuse together into a heavier nucleus. In the reaction, the total mass of the initial nuclei is less than the total mass of the final nucleus, so part of the mass has been converted into energy, according to the equation:
where
is the energy released
c is the speed of light
is the mass defect, which is the mass difference between reactants and products.
Since the factor is very large, we can see that the amount of energy released by a process of nuclear fusion is huge.
An example of nuclear fusion is the fusion of hydrogen nuclei into helium. This process occurs in the core of the stars, and it is the main process through which stars produce energy. In order to occur, the temperature inside the core must be at the order of several million degrees, because the nuclei must overcome the electrostatic repulsion between them, so that they can come close enough to fuse together: for this reason, nuclear fusion is difficult to achieve on Earth, since it is very challenging to recreate the same conditions of temperature and pressure that we have in the core of the stars.
Answer:
Hello there! :) All of these are molecular formulas but F2.
Explanation:
F2 goes by the name flourine and is not F2 in it's chemical makeup. Na2SO4 is also called Sodium Sulfate and is a molecular formula. Everyone knows what H2O is, the molecular formula for water and lastly CO2 is carbon dioxide. Hope this helps!
Answer:
24 molecules of phosphorus trichloride can be formed
Explanation:
Based on the equation:
P4(s) + 6Cl2(g) → 4PCl3
<em>1 mole of P4 reacts with 6 moles of Cl2 to produce 4 moles of PCl3.</em>
<em />
When 10 molecules of P4 react, 60 molecules of Chlorine are needed. As there are just 36 molecules, Cl2 is limiting reactant.
If 36 molecules of chlorine are added, molecules of PCl3 produced are:
36 molecules Cl2 * (4 PCl3 / 6 Cl2) =
24 molecules of phosphorus trichloride can be formed
A molecular formula tells us the atoms involved in bond, what kind of atoms are involved and the ordinality of the atoms. This tells the number of atoms found in the molecule. This can be used to derive the stoichiometric ratios of different atoms. The answer to this problem is a. True.
