D: the composition of the materials that make up the planet
Answer:
The more the temperature the less the effect if magnet
Here we have to choose the molecule which can generate ion-dipole interaction with ammonia.
The NH₃ will have ion dipole interaction only with b) NaOH.
a) The OCl₂ molecule is highly unstable and remains in a linear state as shown in the figure.
b) The NaOH is purely an ionic compound. There is one lone pair of electron on the nitrogen (N) atom of ammonia and also the N-H bond has dipole moment. Now among the given molecules only NaOH is ionic in nature which remains as Na⁺ and OH⁻. Thus we can expect an ion-dipole interaction between these molecules, it is shown in the figure.
c) SiO₂ is purely an covalent compound the structure is shown in the figure.
d) Methyl iodide (CH₃I) is also a covalent compound.
e) The butanol (C₄H₉OH) is a covalent compound.
So we may expect only ion-dipole interaction with b) NaOH.
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.
