The Kingdom of Chemithia- Part 6

Chemistry Level 4

You continue doing your experiments, supported by the king and the kingdom. You are enjoying your job very much, and many people come to your lab to bear witness to all the experiments you are performing. One regular visitor is Princess Selene, King Antimony's daughter, who has a great interest in chemistry. Every day, Princess Selene visits along with her guards to see the research you're doing. One of the days, the Princess does not show up at her usual time, and you find this very odd. You decide to go up to her chambers to investigate.

When you get there, you are shocked to see that the 2 strong guards are lying unconscious on the floor and the door to Selene's room is wide open! You rush in and see that the Princess is gone, and the kidnapper must have fled through the open window. You ring the alarm bell in the room, and King Antimony and a squadron of guards come running to her room.

King Antimony is hysteric; he can't believe that Selene has been kidnapped! You and the guards start searching for evidence as to who would have done it. Under the Princess's table, you find a folded slip of paper. You open it, and printed neatly is a chemistry question and an intricate seal. You show it to the king, and he immediately recognizes it. "Alkemians! The foul residents of the neighbouring kingdom, who believe in alchemy as a solution to all things, and constantly seek to bring us down!"

The note says that the answer to the question will give the coordinates as to where Princess Selene is being held. The King expectantly looks at you as you read the question.

There are a set of problems, that give the coordinates of the place.

To find x-coordinate. "The number of Fluorine atoms in Cryolite, plus the sum of the ketone positions of the one with the most acidic hydrogen among 3-hexanone, 2,4-hexanedione, 2,5-hexanedione, and 2,3-hexanedione."

To find y-coordinate: "The number of centres in a 'banana bond', multiplied by the number of neutrons emitted when $_{92}U^{235}$ undergoes controlled fission to split into $_{54}Xe^{142}$ and $_{38}Sr^{90}$ "

What are the coordinates of the place where Selene is being held? Input your answer as the sum of the x-coordinate and the y-coordinate.

Eg. If the coordinates are (1,4), input 5 as the answer.

This question is part of my set Tales of Chemithia ! Give it a try; it's a story woven together by Chemistry problems!

The answer is 21.

$Cryolite \ is \ Na_{3}[AlF_{6}]$

$The \ ketone \ with \ the \ most \ acidic \ hydrogen \ is \ 2,4-hexanedione$

$So \ x = 6 + 2 + 4 = 12$

$A \ banana \ bond \ has \ 3 \ centers$

$_{92}^{235}U \longrightarrow _{54}^{142}Xe + _{38}^{90}Sr +3 \ _{0}^{1}n$

$So \ y = 3 \times 3 = 9$

$And \ the \ solution \ is \ 12 + 9 = 21$
