The addition of hydrogen carbonate to bromothymol blue turns the solution blue. Thus, option B is correct.

The balanced equation for the dissociation of bromothymol blue is:

\rm HC_2H_3O_2\;\leftrightharpoons H^+\;+\;C_2H_3O_2^-

The color of dissociated form is yellow and undissociated form is blue.

<h3>What is the final color of solution?</h3>

The addition of hydrogen carbonate results in the dissociated ions as:

\rm H_2CO_3\;\rightarrow\;2\;H^+\;+\;CO_3^-

The dissociation results in the increased hydrogen ion concentration. The undissociated form in the reaction mixture increases.

Thus, the color of the solution will turn blue. Hence, option B is correct.

Explain the general process of nuclear fission. What is created from fission?
aliya0001 [1]
In nuclear fission heavier elements are split to make lighter elements whilst releasing energy. An atom, its nucleus to be more specific, is bombarded with neutrons. The nucleus becomes unstable and it starts to split/decay. It creates the fusion products. Neutrons and lighter elements are released; the neutrons from the nuclei of the atom(s) being split.

Salt domes result when: 1. inland seas dry 2.the pressure of overlying rock forces the salt to rise 3. a layer of sedimentary sa
Ilia_Sergeevich [38]

Answer:

Salt domes result when <u><em>the pressure of overlying rock forces the salt to rise. (Option 2)</em></u>

Explanation:

In geology it is called the gently wavy and rounded relief dome.

Salt has some special properties like rock:

  • Salt has a lower specific gravity in relation to a common mineral.
  • Salts deform plastically and are very mobile.
  • Salts have a high water solubility.

These properties allow, if the pressure is very high, that the salt layers move upwards (due to their lower density). That is, the internal forces produce the elevation of the strata by means of the pressure they exert towards a higher point, generating that the salt looks for its way towards the surface [that is, the salt ascends through the sedimentary layers of the earth's crust, crossing them and deforming them] and causing the bulging structure. The oldest strata are located in the central area of the dome, while the most modern are distributed in the farthest radius. The structure is called salt or diapiro dome, the phenomenon by which it is formed is called diapirism.

Finally, you can say that <u><em>Salt domes result when the pressure of overlying rock forces the salt to rise.</em></u>
