11. In TLC analysis of ferrocene and acetylferrocene (on silica TLC plate) which prediction is correct: A) ferrocene is more pol
yaroslaw [1]

Answer:

Alternative C would be the correct choice.

Explanation:

  • The dual compounds were evaluated on something like a TLC plate through three separate additives in conducting a TLC study of ferrocene versus acetylferrocene.
  • The polar as well as nonpolar ferrocene where nonpolar is about 0.63 with the maximum R_f value, and indeed the polar is somewhere around 0.19 with R_f.
  • TLC plate (30:1 toluene/ethanol) established with.  

The other three choices are not related to the given circumstances. So that option C would be the appropriate choice.

Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reac
tatuchka [14]

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

<h3>Why is the energy released in a reaction?</h3>

Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.

The energy, E released in nuclear reactions is given by the formula below:

E = mc^{2}

where m is the mass of the substance and c is the speed of light.

Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.
