IYC2011 - Oxygen Mystery Cache

This cache is temporarily unavailable.

Hexa Nomos: Hei:

Det ser ut som om denne geocachen trenger tilsyn og/eller vedlikehold fra eier, så inntil videre disabler jeg den. Vær snill å sjekke at geocachen er på riktig sted og i god stand, og utfør eventuelt nødvendig vedlikehold.

Hvis geocacheoppføringen er merket med ikonet som angir at geocachen trenger vedlikehold, en rød nøkkel på hvit bakgrunn, kan ikonet fjernes ved å skrive logg av type «Owner Maintenance». Til slutt skriv en logg av type «Enable Listing» for å aktivere geocacheoppføringen.

Hvis geocacheoppføringen må stå deaktivert en stund, f.eks. fordi du ikke har anledning til å utføre vedlikehold ennå, så er det greit, må du skrive en note på geocachesiden hvor du beskriver situasjonen og angir når geocacheoppføringen kan forventes å være aktiv igjen.

Hvis du ikke ønsker å aktivere geocacheoppføringen igjen, vær snill å arkivere den, slik at en annen spiller kan plassere en geocache her. Hvis du bestemmer deg for å arkivere geocacheoppføringen, vær snill å sjekke stedet og ta med deg geocachen eller eventuelle rester av den så snart som mulig, for å unngå forsøpling.

Har du spørsmål eller kommentarer, ta kontakt med meg eller en av de andre på reviewerteamet.

Det er ønskelig at geocachens eier svarer på denne henvendelsen innen 30 dager. Uten svar fra eier, vil det komme et varsel om mulig arkivering.

English: The cache appears to be in need of owner intervention. I'm temporarily disabling it, to give the owner an opportunity to check on the cache, and take whatever action is necessary. Please respond to this situation in a timely manner (i.e., within 30 days) to prevent the cache from being archived for non-responsiveness.

Med vennlig hilsen

Geocache Description:

This is a cache in the IYC2011-series that is preparing for the
International Year of Chemistry in 2011. They will hopefully
increase chemistry knowledge as well as provide for good cache
experiences.

Each cache in the IYC2011-series contains a clue (on the log
sheet) to find the final IYC2011-cache to be released on
1/1/2011.

Oxygen



Oxygen is represented by the symbol O and with atomic number 8.
It is a member of the chalcogen group on the periodic table, and is a highly reactive nonmetallic period 2 element that readily forms compounds (notably oxides) with almost all other elements. At standard temperature and pressure two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. Oxygen is the third most abundant element in the universe by mass after hydrogen and helium and the most abundant element by mass in the Earth's crust. Diatomic oxygen gas constitutes 20.9% of the volume of air.
All major classes of structural molecules in living organisms, such as proteins, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that comprise animal shells, teeth, and bone. Oxygen in the form of O2 is produced from water by cyanobacteria, algae and plants during photosynthesis and is used in cellular respiration for all complex life. Oxygen is toxic to obligately anaerobic organisms, which were the dominant form of early life on Earth until O2 began to accumulate in the atmosphere 2.5 billion years ago. Another form (allotrope) of oxygen, ozone (O3), helps protect the biosphere from ultraviolet radiation with the high-altitude ozone layer, but is a pollutant near the surface where it is a by-product of smog.




Water (H2O) is the oxide of hydrogen and the most familiar oxygen compound. Hydrogen atoms are covalently bonded to oxygen in a water molecule but also have an additional attraction (about 23.3 kJ·mol-1 per hydrogen atom) to an adjacent oxygen atom in a separate molecule. These hydrogen bonds between water molecules hold them approximately 15% closer than what would be expected in a simple liquid with just van der Waals forces.
For reasons of economy, oxygen is often transported in bulk as a liquid in specially insulated tankers, since one litre of liquefied oxygen is equivalent to 840 liters of gaseous oxygen at atmospheric pressure and 20 °C. Such tankers are used to refill bulk liquid oxygen storage containers, which stand outside hospitals and other institutions with a need for large volumes of pure oxygen gas.
Highly enriched [18O]H2O, with enrichment >95%, is used as target material in cyclotrons for the production of the positron emitter18F for PET-imaging.
