Answer:
Chlorine is found abundantly in earth crust and ocean.
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Chlorine is one of them.
it is greenish-yellow irritating gas.
its melting point is 172.2 K
its boiling point is 238.6 K
It is present in earth crust and ocean abundantly.
In ocean chlorine is found in the form of salt sodium chloride.
About 1.9% mass of sea water consist of chlorine ions.
In earth crust it is present in minerals such as carnallite and sylvite.
it is disinfectant and can kill the bacteria.
it is also used in manufacturing of paper, paints and textile industries.
It is also reported that chlorine can effect the respiratory system, immune system and heart.
Up to some extent it can also effect the organism living in water.
Answer:
Examples of how the ideas can be applied to the issues and practices of hydraulic fracturing for the acquisition of shale gas are;
Reuse; The produced water in obtained from oil and gas well production are reused for fracking, drilling, and if the water is good enough, it can be used for farming
Reduce; The use of recycled brine and water in drilling and fracking process reduces the application of freshwater in the those processes and reduces pollution of natural water sources
Recycle; Recycling involves creating products from waste. In the hydraulic fracturing process approximately 13 percent of the water produced and the flowback water are recycled to be used more than once thereby reducing the net consumption of freshwater
Explanation:
In hydraulic fracturing, also known informally as fracking, is the drilling method used in oil and gas well development process that makes use of water sand and chemical injection through the well bore to open and widen cracks in the bedrock formations in the areas around the wellbore.
She has the sea (water), the sand could be viewed as the geosphere and clearly the biosphere. I think for the environment to apply here I would hope to see something about it in the analysis.
Truly, I could go whichever way on this one.
