KOH, like NaOH, serves as a source of OH −, a highly nucleophilic anion that attacks polar bonds in both inorganic and organic materials. Aqueous KOH saponifies esters: KOH + RCOOR' → RCOOK + R'OH. When R is a long chain, the product is called a potassium soap.
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. "Hottah" rock outcrop on Mars – ancient streambed [1] [2] [3] viewed by the Curiosity Rover (September 12, 2012, white balanced) (raw, close-up, 3-D version). Abundant iron compounds are responsible for the bright brownish-red ...
Mars sample return missions have been proposed that would return material from the surface of Mars back to Earth. The study of surface characteristics (or surface properties and processes [1]) is a broad category of Mars science that examines the nature of the materials making up the Martian surface.
Spotting Mars at opposition is easier than you might think because the planet will stand out due to its color and radiance. Instead of appearing a whitish yellow shade like the stars, it will be a ...
If you catch yourself looking up at the night sky this evening, you might notice what looks like a bright star with an orange tint. That's actually the planet Mars. Here's HLN: 'The planet is ...
NASA's Curiosity rover has been exploring the Gale Crater on Mars since 2012, and in that time has come up with some astounding discoveries that suggest the Red Planet was somewhat Earth-like in ...
Ring Mold Craters are kind of crater on the planet Mars, that look like the ring molds used in baking. They are thought to be caused by an impact into ice. The ice is covered by a layer of debris. They are found in parts of Mars that have buried ice. Laboratory experiments confirm that impacts into ice result in a "ring mold shape".
The surface geology of Mars is somewhere between the basalt or andesite rocks on Earth. This led to the formation of minerals similar to what is found on Earth. The presence of iron oxide gives the surface the “rust” color that is associated with Mars, the Red Planet.
