Answer is: conductivity in solution and solubility in water.
Ionic compounds conduct electricity, because it dissociate in ions and ions conduct electicity.
Ionic substances dissociate in water on cations and anions. For example, dissociation of potassium chloride in water: KCl(aq) → K⁺(aq) + Cl⁻(aq).
Ionic compounds (most of the salts, strong acids and bases) dissolve in water because an ion-dipole interactions.
An ion-dipole is electrostatic interaction between a charged ion (cations and anions) and a molecule that has a dipole (in this example water).
Dipole is a separation of positive and negative charges. In water, hydrogen has positive and oxygen has negative charge.
Force /Area = Pressure
Force = Pressure * Area
Force = 1065 * 17 = 18105 N
weight = 18105 N
I hope this helps!
Answer:
Mg(s)+Zn2+>>>>>Mg2++Zn(s) B
Explanation:
No, all wavelengths/photons of light are emitted from excited electrons.
<h3>What is wavelength?</h3>
Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
When an atom's electrons move to a lower energy state, the atom releases energy in the form of a photon. Depending on the energy involved in the emission process, this photon may or may not occur in the visible range of the electromagnetic spectrum.
Hence, no, all wavelengths/photons of light are emitted from excited electrons.
