Answer is c photosynthesis
<u>Answer:</u> 1.2 moles of carbon dioxide is produced for the given value of oxygen.
<u>Explanation:</u>
The chemical reaction for the combustion of acetylene follows the equation:
By stoichiometry of the reaction:
5 moles of oxygen produces 4 moles of carbon dioxide.
So, 1.5 moles of oxygen will produce = 
of carbon dioxide.
Hence, 1.2 moles of carbon dioxide is produced for the given value of oxygen.
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
