Answer:
D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.
Explanation:
<em>Which of the following statements is INCORRECT? </em>
<em>A. It is not possible to know the exact location of an electron and its exact energy simultaneously.</em> CORRECT. This is known as the Heisenberg's uncertainty principle.
<em>B. The energies of an hydrogen atom's electrons are quantized.</em> CORRECT. According to the modern atomic model, the energy levels are quantized, that is, they have a discrete amount of energy.
<em>C. The wave mechanical model correctly predicts all the energy states and the orbitals available to an electron in an hydrogen atom.</em> CORRECT. The characteristics of the energy levels are explained by Schrödinger's wave equation.
<em>D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.</em> INCORRECT. This was postulated by Bohr's atomic model but it is now considered to be incorrect.
<em>E. Electrons have both wave and particle properties.</em> CORRECT. This is what De Broglie called wave-particle duality.
We can see from the details below that, the value of the solution's molality is 1.14 mol/Kg.
<h3>What is solubility?</h3>
The term solubility has to do with the quantity of solute that is able to dissolve in a given quantity of solvent. We have the solubility of the sodium hydrogen carbonate in water at 20 degrees as 9.6 g/100 g h2o.
Number of moles of sodium hydrogen carbonate = 9.6 g/84 g/mol = 0.114 moles
Number of moles water = 100 g /18 g/mol = 5.55 moles
Mole fraction of sodium hydrogen carbonate is obtainable by the use of the relation;
0.114 moles/0.114 moles + 5.55 moles
= 0.02
Molality of the solution = 0.114 moles/0.1 Kg = 1.14 mol/Kg
