Answer : Bleaching action of SO2 is due to reduction and it is temporary.

Explaination : sulphur dioxide and chlorine are used as bleaching agents. However Bleaching action of chlorine is based on oxidation while that of sulphur is based on reduction.

Sulphour dioxide is used as bleaching agent as it removes oxygen from the coloured substances and makes it colorless (Bleaching action). But atmospheric oxygen slowly occupies removed oxygen and the material regains the color.

Answer:

Bleaching by [tex]SO_2[/tex] is a reduction reaction

Explanation:

As a transient bleaching agent sulfur dioxide is utilized.

• When exposed to [tex]SO_2[/tex] , pigment loses its color and becomes a colorless substance.

• When exposed to air, the colorless reduced product reoxidizes and returns to its former color.

• Sulfur's bleaching impact is dependent on a reduction in the amount of oxygen in the air.

                             [tex]SO_2 +2H_2O[/tex]  →  [tex]H_2SO_4 +2[H](nascent)[/tex]

             Color material +[H]  → Colorless color (in presence of air)

• It is commonly used to bleach delegated materials such as ivory, silk, and wool.
• On the other hand, the bleaching action of Chlorine is permanent due to the  oxidation reaction

Answer:

The GDP calculation accounts for spending on both exports and imports. Thus, a country's GDP is the total of consumer spending (C) plus business investment (I) and government spending (G), plus net exports, which is total exports minus total imports (X – M).

The quantum efficiency of a solar cell is defined as the ratio of the number of electrons in the external circuit produced by an incident photon of a given wavelength. Thus, one can define external and internal quantum efficiencies (denoted by EQE(λ) and IQE(λ), respectively).

Quantum efficiency (QE) is a measure of the effectiveness of an imaging device at converting incident photons into electrons.

Explanation:

• The quantum efficiency of a solar cell is defined as the ratio of the number of electrons in an external circuit to that produced by an incident photon of a given wavelength.
• Thus, one can define the external and internal quantum potentials (denoted by EQE(λ) and IQE(λ) respectively).
• It is defined as the number of signal electrons produced per incident photon.
• In some cases it can exceed 100% (ie when more than one electron is created per incident photon).
• The term quantum efficiency (QE) may apply to the incident photon to changed electron (IPCE) ratio of a photosensitizing device, or it may refer to the TMR effect of a magnetic tunnel junction.
