Answer:
There are 8 valence electrons in an argon atom.
a. chain reaction
Explanation:
In a fission, a chain reaction is one where a neutron embeds itself in the nucleus of an U-235 atom and causes it to break apart. After this, more neutrons are created. The neutrons carry on the cycle by starting the fission process over and over again.
Chain reactions typifies most nuclear reactions taking place in the nucleus of an atom.
They are repeated loops that takes place until an atom reaches it state of stability.
- They are not exclusive to fission reactions alone.
- Chain reactions also takes place during nuclear fusion
- In fusion two atoms combines to produce a single nuclide.
- The steps goes on and on
- This why the sun keeps burning and bursting with energy

The balanced chemical reaction is written as:
<span>2Al2O3 = 4Al + 3O2
We are given the amount of aluminum oxide used in the reaction. This will be the starting point for the calculations. We do as follows:
26.5 mol Al2O3 ( 3 mol O2 / 2 mol Al2O3 ) = 39.75 mol O2 produced</span>
