Bad White [126]

Answer:

The Equations sort each listed half reaction as either an oxidation or a reduction.

Fe + CuSO4 + → FeSO4 + Cu

(Fe oxidized, Cu reduced)

Explanation:

For proper understanding of the concept of the Redox reaction, let us know the meaning:

Reduction- Oxidation or "redox" reactions occur when elements in a chemical reaction gain or lose electrons. This reaction causes an increase or decrease in oxidation numbers. The Half Equation Method is used to balance these reactions. The equation is separated into two half-equations, one for oxidation and one for reduction. For Example -

CuO + H2 → Cu +H2O.

In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed.

Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0.

<span>The more silica crystal within the magma, the viscosity of the magma increases because of crystals sticking present. So when the magma has low silica content, but viscous (sticky, like honey) magma will not, and gas gets trapped within it, and then explodes out, cause large scale explosive erruptions.</span>
