<h3>What is spectrometric method?</h3>
  • A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
  • Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.
  • There are two main techniques used among the various forms of spectrophotometry:
  • ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
  • and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.
  • Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.

Question 1 of 10
Alina [70]

D. The total number of gas molecules will decrease.

Explanation:

According to Le Chatelier's principle, an increase in pressure in a system involving gases will cause the total number of gas molecules to decrease.

Le Chatelier's principle states that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

In a reaction involving gases, a change in pressure affects only reactions in a gaseous phase.

An increase in pressure on an equilibrium system will shift the position of the equilibrium to the side having smaller volume and vice versa.

13. Base your answer to the following question on the information below and on your knowledge of chemistry.
ahrayia [7]

From our knowledge of periodic trends, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.

<h3>Periodic trends</h3>

The periodic trends are those properties that increase or decrease down the group or across the period. These periodic trends include;

  • Ionization energy
  • Electron affinity
  • Atomic radius
  • Ionic radius etc

As more shell are added down the group in group 14, the screening effect of the inner electrons outweigh the increase in nuclear charge causing the atomic radius to increase.
