The quantum numbers can be used to describe a specific electron in an atom of that element. There are four quantum numbers:
<span><span>n, the principal quantum number, which describes the shell of an electron;</span><span>l, the Azimuthal quantum number, which describes the subshell of an electron;</span><span><span>ml</span>, the magnetic quantum number, which describes/specifies the orbital an electron is in; and</span><span><span>ms</span>, the spin quantum number, which describes the spin of the electron.</span></span>
For example, if I was told that I had quantum numbers for a valence shell electron in the ground state for nitrogen were <span>n=2,l=1,<span>ml</span>=−1</span> and <span><span>ms</span>=+<span>12</span></span> then:
<span><span>The <span>n=2</span> tells me that we are describing a shell 2 electron.</span>the <span>l=1</span> describes the subshell as p.
I now know we are talking about a shell 2, p subshell energy level for the electron.The <span><span>ml</span>=−1</span> would indicate the specific orbital in the p-subshell (there are three possible p-orbitals in this p-subshell with <span>ml</span> values = -1, 0, +1)We have specified the first 2p-subshell orbital with the <span>ml</span> value = -1. The spin quantum number of +1/2 indicates one of two possible spin quantum numbers (+1/2 and -1/2) for the two electrons that can fill this specific orbital in this specific subshell and shell.</span>
Answer:
Two thirds the number of moles of hydrogen
Explanation:
The balanced reaction is
3H₂ + N₂ → 2NH₃
So 1 mol of nitrogen gas reacts completely with 3 moles of hydrogen gas, to produce 2 moles of ammonia.
If equal moles of nitrogen and hydrogen are combined, <em>then hydrogen would be the limiting reactant</em>. Let's say we have 3 moles of each reactant, one mol of N₂ reacts with the 3 moles of H₂ and produces 2 moles of NH₃, and 2 moles of N₂ would remain. So the answer is<em> two thirds the number of moles of hydrogen.</em>

Answer:
C. Deductive reasoning
Explanation:
Deductive reasoning is a reasoning or logical process whereby a conclusion is drawn based on the belief of multiple premises that are generally assumed to be true. It is a logical process in which one or multiple statements reaches a logical conclusion.
In the question, the statement assumed to be true is that <em>noble gases are unreactive because of their electronic structures.</em>
The conclusion thus drawn from the premise is that <em>if other elements could be made to achieve noble gases electronic structures (</em><u><em>this is the reason why they are unreactive - the fact)</em></u><em> they would be more stable.</em>
<em />
Therefore, deductive reasoning moves from a wilder reasoning to a specific (narrower) reasoning.
