It is written as Al(Hg) in reactions. [1] Al(Hg) may be prepared by either grinding aluminium pellets or wire in mercury, or by allowing aluminium wire to react with a solution of mercury(II) chloride in water. [2] [3] [1] This amalgam is used as a chemical reagent to reduce compounds, such as of imines to amines. The aluminium is the ultimate ...
Mold is a dangerous library pest because of the damage it causes to the collections. Mold thrives off of paper and books; these objects provide the fungi a source of nutrition, namely the sugar and starches present in the cellulose materials. [6] Mold feeds on cloth, leather, glues, adhesives, cellulose starch and starches in the sizing.

Removal of affected materials after the source of moisture has been reduced and/or eliminated may be necessary, as some materials cannot be remediated. [55] Thus, the concept of mold growth, assessment, and remediation is essential in preventing health issues arising due to the presence of dampness and mold.
Mercury(II) fulminate, or Hg(CNO) 2, is a primary explosive. It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and detonators. Mercury(II) cyanate, though its chemical formula is identical, has a different atomic arrangement, making the cyanate and fulminate anionic isomers.
