Answer:
The value is
Explanation:
From the question we are told that
The equilibrium spacing is
The mass of a hydrogen atom is
The principal quantum number of the second energy level is
The principal quantum number of the first energy level is
Given that the hydrogen molecule is a symmetrical diatomic molecule, its moment of inertia is mathematically represented as
Generally for rotational spectrum the energy level is mathematically represented as
Generally the energy difference between the first energy level and the second energy level is mathematically represented as
=>
=>
substituting for I
=>
Generally this difference in energy level can also be mathematically represented as
=>
=>
Here h is Planck's constant with value
and c is the speed of light with value
So
=>
=>
=>
The moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.
The balanced chemical equation for the decomposition of Ammonia has been:
<h3>Computation for moles of Hydrogen produced</h3>
From the balanced chemical equation, decomposition of 2 moles of ammonia produces, 3 moles of hydrogen and 1 mole, nitrogen.
The moles of hydrogen produced along with 0.0351 mol nitrogen has been:
Thus, the moles of hydrogen produced in the reaction has been 0.105 mol. Hence, option D is correct.

E) iii and iv
The answer is A.
Explanation:
A redox reaction i.e. oxidation-reduction is a reaction in which a change in the oxidation number or state of the participating atoms occur. A redox reaction, as the name implies, contains the oxidation part and the reduction part.
Just like any other reaction, redox reaction needs to be balanced as well. A balanced redox reaction must have the following characteristics:
- The same number of each type of atom on both sides of the equation. For example, if there are 4 atoms of Carbon on the reactant side, there must be 4 atoms of C on product side.
- The total number electrons lost in the oxidation equal to total number of electrons gained in the reduction. For example, if 12 electrons are gained in the reduction part, 12 electrons must be lost in the oxidation part.
- The same total charge of all ionic species on both sides of the reaction.
The correct answer is D. melting the solid.
