Carbon monoxide (CO), also referred to as carbonous oxide, is a colorless, odorless, and tasteless gas that is slightly lighter than air. Ni + 4CO Ni(CO)4 (Nickel tetracarbonyl) Then, the obtained nickel tetracarbonyl is decomposed by subjecting it to a higher temperature (450 - 470 K) to obtain pure nickel metal. Because of carbon monoxide's role in the body, abnormalities in its metabolism have been linked to a variety of diseases, including neurodegenerations, hypertension, heart failure, and pathological inflammation. Exposure to high levels of carbon monoxide is extremely toxic to humans and animals. The color persists even upon thawing and holding near room temperature thus preserving the fresh look of the product. i] Displaces hydrogen from very dilute nitric acid In the Monsanto process, carbon monoxide and methanol react in the presence of a homogeneous rhodium catalyst and hydroiodic acid to give acetic acid.
