The answer is Alfred Wallace.
Darwin began formulating his theory of natural selection in the late 1830s but he went on working silently on it for twenty years. He wanted to amass a wealth of evidence before publicly presenting his idea. During those years he corresponded briefly with Wallace (right), who was exploring the wildlife of South America and Asia. Wallace supplied Darwin's help publishing his own ideas on evolution. He sent Darwin his theory in 1858, which, to Darwin's shock, nearly replicated Darwin's own.

A. what is hard water? why is the presence of hard water often considered a negative thing? (3 points)

Anna35 [415]

Hard water contains mineral ions basically the calcium and magnesium ions.

The presence of hard water often considered a negative thing as it is associated with a number of issues related to plumbing, water storage as well as cleaning and maintenance.

Hard water leads to clogged pipes due to the deposition of ions on the surface of water conducting pipes. This hindrance also degrades the quality of equipment used for water storage and heating e.g. geysers.

The hardness of water can either be temporary or permanent depending on the type of ions present in it. Temporary hard water contains calcium and magnesium ions whereas Permanent hard water contains anions like the sulfate ion.
