Answer:
The period number tells which is the highest energy level occupied by the electrons.
Explanation:
- The period number (denoted by n) is the outer energy level that is occupied by electrons in an atom.
- The period number that an element is in, is the number of energy levels that the element has.
- When we move across a period from left to right in a periodic table the number of electrons in atoms increases within the same orbit.
The collision and decomposition of 2 ammonium nitrate molecules results in the formation of 2 molecules of and 4 molecules of
<h3>Decomposition reaction</h3>
Ammonium nitrate decomposes to produce nitrous oxide and water according to the following equation:
In the above, a mole of ammonium nitrate decomposes to form a mole of nitrous oxide and 2 moles of water.
If moles of ammonium nitrate decomposes, the equation becomes:
Thus, 2 moles of nitrous oxide and 4 moles of water would be formed.
