Assuming that both cases describe hydrogen‑like atoms with one electron, More energy is emitted or absorbed for case 2. The correct option is D.
<h3>What is emitting of energy, by electron?</h3>
The energy of the electron decreases as it changes levels, and emission of photons happens in the atom.
With the electron moving from a higher to a lower energy level, the photon is emitted. The photon's energy is the same as the energy lost by an electron moving to a lower energy level.
Thus, the correct option is D, More energy is emitted or absorbed for case 2.

Answer:
30.83 M
Explanation:
17.03052 re in one mole. So, if you multiply it by 30.83, you will get 535 g of ammonia.
In fact, the detailed answer is 30.827009392549122.
Answer:
hexaaquairon(III) trinitrate
The true ratio of atoms in a molecule or formula unit is called molecular formula
<h3>What is empirical formula?</h3>
This is the simplest formula that shows the ratio of the different atoms present in a compound.
<h3>What is molecular formula?</h3>
This is the formula of a compound which gives the true or actual ratios of the different atoms present in a compound
<h3>What is molar mass?</h3>
The molar mass of a compound is defined as the sum total of the molar masses of the different atoms present in the compound.
<h3>What is percentage composition?</h3>
This gives the proportion of the different atoms present in a compound.
From the above definitions, we can conclude that the correct answer to the question is molecular formula

D. Zn + Ca²⁺ → Zn²⁺ + Ca
Because Ca is more active metal (from the electrochemical series).
