Materials of low mass are combined to form a substance of higher mass during ____. a. fission c. both A and B b. fusion d. neith
Andrei [34K]
<h2>The required "option is b) Fusion"</h2>

Explanation:

  • During fission, the nucleus of higher mass is broken down into the nucleus of lower mass in which a high amount of energy is released.
  • During fusion two nuclei combine or fuses to form a larger molecule of higher mass for which a high amount of energy is provided.
  • Therefore, the higher mass of a substance is formed with the combination of lower mass of a substance during the process of fusion.
  • Hence, the required option is Fusion.

A complex, ML₆²⁺, is violet. The same metal forms a complex with another ligand, Q, that creates a weaker field. What color migh
Bingel [31]

A complex, ML₆²⁺, is violet. The same metal forms a complex with another ligand, Q, that creates a weaker field.  MQ₆²⁺, be expected to show green color.

<h3>What is spectrochemical series?</h3>

The ligands (attachment to a metal ion) are listed in the spectrochemical series according to the strength of their field. The series has been created by superimposing several sequences discovered through spectroscopic research because it is impossible to produce the full series by examining complexes with a single metal ion. The halides are referred to be weak-field ligands whereas the ligands cyanide and CO are strong-field ligands. Medium field effects are claimed to be produced by ligands like water and ammonia.
