Is copper penny react<br> reaction with Nitric<br> acid a<br> Chemical or physical<br> Change?
riadik2000 [5.3K]

Answer:

The reaction that occurs is a redox reaction. The Copper metal (Cu 0)on the copper pennies is oxidized in concentrated nitric acid to produce Cu2+ ions. Copper is easily oxidized to Cu2+, which is blue in aqueous solutions (water) so you should see the solution turn blue as the copper penny reacts.

Have a nice day ;)(^-^)

A woolly mammoth was found in 1999 buried in the frozen soil of the Siberian tundra. Carbon-14 dating indicated that it had died
klemol [59]

Tundra soils are formed at high latitudes which leaves the tundra always very cold. Tundra soils are generally frozen, and are classifed as Gelisols (this means that permafrost are within 100 cm of the soil surface). These permafrost are as a result of the freezing by winter of the underground water that was accumulated in summer. These soils freeze and thaw alot and as result of that, moisture do not permeate the soil easily. Also, due to this harsh temperature and underground permafrost, most organisms that died in the tundra are preserved within the soil.
