Scientists once thought there was no life on the deep-sea floor due to the lack of sunlight. However, in the 1970's, complete ecosystems were discovered on the deep-sea floor that depend on energy from chemical reactions rather than energy from sunlight. Which conclusion can be drawn from this discovery? A organisms are able to survive under any conditions.
B Observations will always lead to the discovery of new organisms.
C Organisms may be discovered in remote areas and extreme conditions.
D Observations collected on existing organisms can be applied to any organism.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
