Dinitrogen trioxide - Wikipedia

Dinitrogen trioxide is the chemical compound with the formula N 2 O 3. This deep blue solid is one of the simple nitrogen oxides. It forms upon mixing equal parts of nitric oxide and nitrogen dioxide and cooling the mixture below −21 °C (−6 °F): NO + NO 2 ⇌ N 2 O 3.

WebElements Periodic Table » Antimony » reactions of elements

Upon heating, antimony reacts with oxygen in air to form the trioxide antimony(III) oxide, Sb 2 O 3. The flame is bluish white. 4Sb(s) + 3O 2 (g) → 2sb 2 O 3 (s) Reaction of antimony with water. At red heat, antimony reacts with water to form the trioxide antimony(III) oxide, Sb 2 O 3. Antimony reacts moreslowly at ambient temperatures.

Antimony - Wikipedia

Antimony is a member of group 15 of the periodic table, one of the elements called pnictogens, and has an electronegativity of 2.05. In accordance with periodic trends, it is more electronegative than tin or bismuth, and less electronegative than tellurium or arsenic.Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb 2 O 3.
