Enjoying the "chemistry series"? If you have found several of the park and grab caches from this series, don't expect the same hide here. Parking can be found .14mi from the cache (N41° 10.349 W96° 9.701). You can follow the paved walking path to within a few feet of ground zero, but be aware of who may be watching before making the grab.
This is part of a series of caches all using the same container. The experiment continues... first, the container was proven to be waterproof as long as you replace the lid tightly (please do). Second, they seem to be holding up in the elements, at least for the short term. No real complaints about the internal log construction... now it is time to get a bit more creative with the camouflage and find some more interesting places to hide these. Hope you enjoy this one.
************************* COPPER *************************
Atomic Number: 29
Symbol: Cu
Discovery: Copper has been known since prehistoric time. It has been mined for more than 5000 years.
Word Origin: Latin cuprum: from the isle of Cyprus, which is famed for its copper mines
Properties: Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat. It is second only to silver as an electrical conductor.
Uses: Copper is widely used in the electrical industry. In addition to many other uses, copper is used in plumbing and for cookware. Brass and bronze are two important copper alloys. Copper compounds are toxic to invertebrates and are used as algicides and pesticides. Copper compounds are used in analytical chemistry, as in the use of Fehling's solution to test for sugar. American coins contain copper.
Sources: Sometimes copper appears in its native state. It is found in many minerals, including malachite, cuprite, bornite, azurite, and chalcopyrite. Copper ore deposits are known in North America, South America, and Africa. Copper is obtained by smelting, leaching, and electrolysis of the copper sulfides, oxides, and carbonates. Copper is commercially available at a purity of 99.999+ %.
