Upon heating in air to 50 °C, the tetrahydrate transforms into the dihydrate, which at 60 °C further converts to Sc 4 O 3 (NO 3) 3 ·6.5H 2 O. At 140–220 °C, Sc 4 O 5 (NO 3) 3 is formed. [2] Scandium nitrate has been found to form clusters when in an aqueous solution which can affect its behavior and properties in various ways.

South Carolina Highway 3 (SC 3) is a 96.310-mile (154.996 km) state highway in the southern part of the U.S. state of South Carolina. The highway travels in a C-shape from a point approximately 11 miles (18 km) southeast of Varnville northwest and north to Barnwell , and then northeast to Swansea .
In all four halides, the scandium is 6-coordinated. They can be prepared by reacting scandium oxide or scandium hydroxide with the corresponding acid: [3] Sc(OH) 3 + 3 HX → ScX 3 + 3 H 2 O. The halides are Lewis acids; for example, ScF 3 dissolves in a solution containing excess fluoride ion to form [ScF 6] 3−. The coordination number 6 is ...
Scandium trifluoromethanesulfonate, commonly called scandium triflate, is a chemical compound with formula Sc(SO 3 CF 3) 3, a salt consisting of scandium cations Sc 3+ and triflate SO 3 CF − 3 anions. Scandium triflate is used as a reagent in organic chemistry as a Lewis acid. [1]

South Carolina was the first state to ratify the Articles of Confederation, the 8th state to ratify the US Constitution on May 23, 1788. South Carolina later became the first state to vote to secede from the Union which it did on December 20, 1860. It was readmitted to the United States on June 25, 1868. [note 1]
Scandium(III) oxide or scandia is a inorganic compound with formula Sc 2 O 3.It is one of several oxides of rare earth elements with a high melting point.It is used in the preparation of other scandium compounds as well as in high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition (as a helper material).
