Contrast the silica content of magma in quiet and explosive eruptions
klemol [59]
Magma in quiet eruptions has a low content in silica , while in explosive eruptions, it has a high Content in silica.  A volcano that erupts quietly has  magma that is low in silica. Low-silica magma has low viscosity and flows easily.  A volcano that erupts explosively has magma that is high in silica. High-silica magma has high viscosity, making it thick and sticky, thus it flows slowly.

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the __________; the chemical
Romashka [77]

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the <u>cathode</u>; the chemical change that occurs at this electrode is called <u>reduction</u>.

<h3>Define Electrolyte:-</h3>

An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.

<h3>Electrochemical cell </h3>

There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements

  • The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.
  • The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.
  • A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.
  • Anode and cathode are connected by the conductor, which also completes the circuit.
