All of the F's sublevels, including the 5F contains 7 orbitals. Then, each orbital should contain 2 electrons. From the given above, the number of electrons in the sublevel is calculated through,
n = (7 orbitals) x (2 electrons / orbital) = 14 electrons
Thus, the 5F sublevel contains 14 electrons.
Independent Variable: amount of sunlight given
Dependent Variable: How tall the plants grow
Control: The plant given no sunlight
The Kelvin Scale is used, so the answer is temperature :)
Answer:
<em>Scheme attached</em>
Explanation:
<em>Trans</em> effect is involved in this synthesis. As in the reactions of planer metal complexes, trans effect dominates the stereo-chemistry of the product.
<em>Trans</em> effect
The role of the element present in trans position to the element to be substituted is called the trans effect. The nature of the ligand in trans position effects the substitution, if it has high <em>trans</em> effect it make the substitution difficult.
So when we attach NH₃ first to the ligand it make the trans substitution difficult, hence <em>cis</em> product will be formed.
As NO₂ has very low <em>trans</em> effect, so it doesn't effect the substitution and the <em>trans</em> product will be formed as usual.
Answer is: mass of ammonia is 17 grams.
Chemical reaction: 3H₂ + N₂ → 2NH₃.
m(N₂) = 14,01 g.
n(N₂) = m(N₂) ÷ M(N₂).
n(N₂) = 14,01 g ÷ 28,02.
n(N₂) = 0,5 mol.
m(H₂) = 3,02 g.
n(H₂) = 3,02 g ÷ 2,01 g/mol.
n(H₂) = 1,5 mol.
From chemical reaction: n(N₂) : n(H₂) = 1 : 3.
From chemical reaction: n(N₂) : n(NH₃) = 1 : 2.
n(NH₃) = 2 · 0,5 mol = 1 mol.
m(NH₃) = 1 mol · 17 g/mol.
m(NH₃) = 17 g.
