This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Mass–energy equivalence states that all objects having mass, or massive objects, have a corresponding intrinsic energy, even when they are stationary.In the rest frame of an object, where by definition it is motionless and so has no momentum, the mass and energy are equal or they differ only by a constant factor, the speed of light squared (c 2).
NGC 522, also occasionally referred to as PGC 5218 or UGC 970, is a spiral galaxy located approximately 122 million light-years from the Solar System [3] in the constellation Pisces. [2] It was discovered on 25 September 1862 by astronomer Heinrich Louis d'Arrest .
The density at the surface is 65 kg/m 3 (4.1 lb/cu ft), 6.5% that of water [88] or 50 times as dense as Earth's atmosphere at 293 K (20 °C; 68 °F) at sea level. The CO 2-rich atmosphere generates the strongest greenhouse effect in the Solar System, creating surface temperatures of at least 735 K (462 °C; 864 °F).
Car 9 is designated as "Green car" (first class) accommodation with 55 seats arranged in 2+2 abreast configuration. Seat pitch is 1,160 mm (45.7 in). [22] Seats are 475 mm (18.7 in) wide and recline to an angle of 31 degrees. [23] The carpet in the H5 series's Green car is dark grey with a pattern depicting the ocean with fragments of drift ice ...
[2] [3] The median age of women tends to be much greater than that of men in some of the ex-Soviet republics, while in the Global South, the difference is far smaller or is reversed. In this article, two sets of data based on Central Intelligence Agency (CIA) and United Nations (UN) estimates are provided.
2 I − + 2 Fe 3+ → I 2 + 2 Fe 2+ (E 0 = +0.23 V) Ferric iodide, a black solid, is not stable in ordinary conditions, but can be prepared through the reaction of iron pentacarbonyl with iodine and carbon monoxide in the presence of hexane and light at the temperature of −20 °C, with oxygen and water excluded.

Canarium can also grow in sub-tropical regions with temperatures from 17–25 °C (63–77 °F). [2] However, it is sensitive to temperatures below 5–7 °C (41–45 °F) and frost. Trees mainly grow from sea level to 250 m (820 ft), but may be planted up 600 m (2,000 ft). [1] In the wild, it is found up to 100 m (330 ft) above sea level. [2]
