An Introduction To Water Hardness | ITACA

Since calcium carbonate is much less soluble in water than calcium bicarbonate it precipitates out of solution as a solid known as scale or lime scale. Because this type of hardness is easily removed (i.e. by simple heating) it is known as temporary hardness. Scale normally appears around heating elements and hot water systems.

Alloys - What are they? What are common alloys …

You might see the word alloy described as a "mixture of metals", but that''s a little bit misleading because some alloys contain only one metal and it''s mixed in with other substances that are nonmetals (cast iron, for example, is an alloy made of just one metal, iron, mixed with one nonmetal, carbon).
