Answer:
12 moles of water will be produced
Explanation:
Given data:
Number of moles of NH₃ = 8.00 mol
Number of moles of O₂ = 14.0 mol
Number of moles of H₂O produced = ?
Solution:
Chemical equation:
4NH₃ + 7O₂ → 4NO₂ +6H₂O
Now we will compare the moles of reactant with product.
NH₃ : H₂O
4 : 6
8 : 6/4×8 = 12
O₂ : H₂O
7 : 6
14 : 6/7×14 = 12
12 moles of water will be produced.
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 units tell you:
g/cm³ = Mass (in grams) per (divided by) Volume (in cm³);
So:
109/24 = 4.54166..... ⇒ 4.54 g/cm³.
Always look at the units.
Just like for speed, you might have m/s so this is:
Distance (in meters) per (divided by) Time (in seconds).
