question:
Bloodstone, agate, and onyx are chalcedonic varieties of this mineral. Other color variations arise from substituting atoms for silicon; iron for citrine and amethysts, titanium for the rose variety. When cemented it makes sandstone and when fused, silica glass. For ten points, identify this mineral composed of crystalline silicon dioxide.
answer:
Science


question:
One party in this conflict was led for part of it by the namesake of a battleship famous in a later conflict, the Duke of Caxias. This clash was precipitated by the ouster of Atansio Aguirre. Victory at Curupayty forestalled defeat for the eventual losers, whose fate was practically sealed after the naval Battle of Riachuelo. This war's namesake treaty was the brainchild of Bartolom Mitre, who favored the Colorado Party over the Blanco Party in Uruguay. FTP, name this conflict in which Paraguay under Francisco Solano Lpez was eventually defeated by the namesake entity, consisting of Argentina, Brazil, and Uruguay.
answer:
History


question:
The Fermi distribution is used over the Curie relation in gauging this phenomenon in metals, resulting in a smaller susceptibility. This phenomenon contributes an induced field that adds to the applied field, and the resulting alignment tends to compete with thermal motion, thereby randomizing the dipole orientations. The dipoles interact weakly with each other in the absence of an external field. Occurring in free radicals and transition-metal compounds, FTP, identify this type of magnetism occurring in all atoms with free electrons whose spin moments are aligned with an external magnetic field.
answer:

Science
