Iron(II) carbonate, or ferrous carbonate, is a chemical compound with formula FeCO 3, that occurs naturally as the mineral siderite. At ordinary ambient temperatures, it is a green-brown ionic solid consisting of iron(II) cations Fe 2+ and carbonate anions CO 2− 3. [5]
Siderite is a mineral composed of iron(II) carbonate (FeCO 3).Its name comes from the Ancient Greek word σίδηρος (sídēros), meaning "iron".A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus.
Nitric acid is an inorganic compound with the formula H N O 3.It is a highly corrosive mineral acid. [6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen.
electropositive metals with values between 1.4 and 1.9; and electronegative metals with values between 1.9 and 2.54. From the image, the group 1–2 metals and the lanthanides and actinides are very electropositive to electropositive; the transition metals in groups 3 to 12 are very electropositive to electronegative; and the post-transition ...
Anhydrous nitric acid may be made by distilling concentrated nitric acid with phosphorus pentoxide at low pressure in glass apparatus in the dark. It can only be made in the solid state, because upon melting it spontaneously decomposes to nitrogen dioxide, and liquid nitric acid undergoes self-ionisation to a larger extent than any other ...
Being the conjugate base of a strong acid (nitric acid, pK a = -1.4), nitrate has modest Lewis basicity.Two coordination modes are common: unidentate and bidentate.Often, bidentate nitrate, denoted κ 2-NO 3, is bound unsymmetrically in the sense that one M-O distance is clearly bonding and the other is more weakly interacting.

An American Airlines flight departing New York's LaGuardia Airport on Thursday evening had to divert to nearby John F. Kennedy International shortly after takeoff after a reported bird strike ...
In the 1830s, Michael Faraday and Christian Friedrich Schönbein studied that issue systematically and demonstrated that when a piece of iron is placed in dilute nitric acid, it will dissolve and produce hydrogen, but if the iron is placed in concentrated nitric acid and then returned to the dilute nitric acid, little or no reaction will take ...
