Hexavalent chromium (chromium(VI), Cr(VI), chromium 6) is any chemical compound that contains the element chromium in the +6 oxidation state (thus hexavalent). [1] It has been identified as carcinogenic, which is of concern since approximately 136,000 tonnes (150,000 tons) of hexavalent chromium were produced in 1985. [ 2 ]
Trivalent chromium plating, also known as tri-chrome, Cr 3+, and chrome(III) plating, uses chromium sulfate or chromium chloride as the main ingredient. Trivalent chromium plating is an alternative to hexavalent chromium in certain applications and thicknesses (e.g. decorative plating). [2]
3 has the corundum structure, consisting of a hexagonal close packed array of oxide anions with 2 ⁄ 3 of the octahedral holes occupied by chromium. Similar to corundum, Cr 2 O 3 is a hard, brittle material (Mohs hardness 8 to 8.5). [4] It is antiferromagnetic up to 307 K, the Néel temperature. [5] [6] It is not readily attacked by acids.
Chromium is a free and open-source web browser project, primarily developed and maintained by Google. [3] It is a widely-used codebase, providing the vast majority of code for Google Chrome and many other browsers, including Microsoft Edge, Samsung Internet, and Opera.
Once upon a time, Google Chrome was atop the internet browser food chain with its simplistic design, easy access to Google Search, and customizable layout. In 2020, most browsers have adapted.
The M15 was based on the M3 half-track chassis, adding a coaxially mounted armament of a fully automatic M1 37 mm (1.5 in) gun and two superior-placed .50-caliber (12.7 mm) M2 Browning machine guns. [3] Manned by a crew of seven, [4] it was 20 feet 3 inches (6.17 m) long, 7 feet 4 inches (2.24 m) wide, and 7 feet 10 inches (2.39 m) high, and ...

Browsers are compiled to run on certain operating systems, without emulation.. This list is not exhaustive, but rather reflects the most common OSes today (e.g. Netscape Navigator was also developed for OS/2 at a time when macOS 10 did not exist) but does not include the growing appliance segment (for example, the Opera web browser has gained a leading role for use in mobile phones ...
