Strontium nitrate is an inorganic compound composed of the elements strontium, nitrogen and oxygen with the formula Sr(NO 3) 2. This colorless solid is used as a red colorant and oxidizer in pyrotechnics .
Thermal decomposition, or thermolysis, is a chemical decomposition of a substance caused by heat. The decomposition temperature of a substance is the temperature at which the substance chemically decomposes. The reaction is usually endothermic as heat is required to break chemical bonds in the compound undergoing
Samarium(III) nitrate is an odorless, white-colored chemical compound with the formula Sm(NO 3) 3. It forms the hexahydrate, which decomposes at 50°C to the anhydrous form. When further heated to 420°C, it is converted to the oxynitrate, and at 680°C it decomposes to form samarium(III) oxide. [2]
It has good thermal stability, and its solubility product pK sp,c is 21.86±0.11. [11] Neodymium(III) oxalate is a rose-coloured crystal which decomposes from its decahydrate to its anhydrous form when heated, and when heated further, decomposes to Nd 2 O 2 C 2 O 4, [12] and then finally obtaining neodymium(III) oxide. [13]
The alkaline earth metal oxides are formed from the thermal decomposition of the corresponding carbonates. CaCO 3 → CaO + CO 2 (at approx. 900°C) In laboratory, they are obtained from hydroxides: Mg(OH) 2 → MgO + H 2 O. or nitrates: Ca(NO 3) 2 → CaO + 2NO 2 + 1/2O 2. The oxides exhibit basic character: they turn phenolphthalein red and ...
Kidney disease results from kidney damage and subsequent decline in kidney function.
thermal decomposition of samarium(III) carbonate, hydroxide, nitrate, oxalate or sulfate: Sm 2 (CO 3) 3 → Sm 2 O 3 + 3 CO 2. 2. by burning the metal in air or oxygen at a temperature above 150 °C: 4 Sm + 3 O 2 → 2 Sm 2 O 3
