Explain the conductivity results observed for sodium chloride in the solid state and in aqueous solution
Fittoniya [83]

NaCl when in solid state does not conduct electricity while it does in aqueous solution.

Explanation:

NaCl (or what we call common salt) first needs to be either melted or dissolved in a solution for it to conduct electricity. The reason for this is that electrons in a solid state does not have enough freedom to move to either the Cathode (-ve) or to the Anode (+ve). So in a liquid state the electrons are now free enough to move.

What creates Earth’s magnetic field?
DIA [1.3K]
Earth's magnetic field doesn't have much to do with tectonic plates. But both are caused by movement of the magma. The magnetic field is caused by electrical currents flowing in the magma, roughly parallel with the Equator. Tectonic plates move around the surface of the Earth over the liquid magma.

So I'd go with B. mantle convection currents

If you flow a solution of Mg CO3-- in water over a Cation resin, what will be in the outlet stream leaving the bed
vodka [1.7K]

In a a cation-exchange resin, the outlet stream leaving the bed will contain H^{+} and CO_3 ^{2-}.

<h3>What is cation-exchange resin?</h3>
  • A resin or polymer that serves as a medium for ion exchange is known as an ion-exchange resin or cation-exchange resin.
  • It is an insoluble matrix (or support structure) made from an organic polymer substrate, typically appearing as tiny (0.25-1.43 mm radius) microbeads that are white or yellowish in color.
  • The process is known as cation-exchange resin because the beads are often porous, providing a wide surface area on and inside them where the trapping of ions takes place along with the concomitant release of other ions.
  • cation-exchange resin comes in many different varieties. Polystyrene sulfonate is the main ingredient in most commercial resins. Many diverse separation, purification, and decontamination techniques use cation-exchange resin.
  • The most typical examples are water filtration and water softening.
