Quick park and grab in Applewood Park. You can park just a few feet from ground zero. Lots of muggles around at times, so be aware of who may be watching before making the grab. Bring your own pen/pencil. The park is closed from 11pm to 5am.
This is part of a series of caches all using the same container. Someone was throwing out a whole sack of these containers. I'm not sure how it will stand up to the elements, but I thought I would do some experimenting. By submerging the container underwater for several minutes, I proved it was waterproof... as long as the lid is replaced tightly, so please do that. The second part of the experiment is putting some out in the wild... we'll see how they do.
************************* NITROGEN *************************
Symbol: N
Atomic Number: 7
Nitrogen Discovery: Daniel Rutherford 1772 (Scotland): Rutherford removed oxygen and carbon dioxide from air and showed that the residual gas would not support combustion or living organisms.
Word Origin: Latin: nitrum, Greek: nitron and genes; native soda, forming. Nitrogen was sometimes referred to as 'burnt' or 'dephlogisticated' air. The French chemist Antoine Laurent Lavoisier named nitrogen azote, meaning without life.
Properties: Nitrogen gas is colorless, odorless, and relatively inert. Liquid nitrogen is also colorless and odorless, and is similar in appearance to water. There are two allotropic forms of solid nitrogen, a and b, with a transition between the two forms at -237° C. Nitrogen's melting point is -209.86° C, boiling point is -195.8° C, density is 1.2506 g/l, specific gravity is 0.0808 (-195.8° C) for the liquid and 1.026 (-252° C) for the solid. Nitrogen has a valence of 3 or 5.
Uses: Nitrogen compounds are found in foods, fertilizers, poisons, and explosives. Nitrogen gas is used as a blanketing medium during the production of electronic components. Nitrogen is also used in annealing stainless steels and other steel products. Liquid nitrogen is used as a refrigerant. Although nitrogen gas is fairly inert, soil bacteria can 'fix' nitrogen into a usable form, which plants and animals can then utilize. Nitrogen is a component of all proteins. Nitrogen is responsible for the orange-red, blue-green, blue-violet, and deep violet colors of the aurora.
