of a solution of 224 g (1.65 mol) of potassium hydrogensulfate in 1.5 L ofwater. The acidification is accompanied by copious evolution of carbon dioxide. The turbid reaction mixture is thenextracted with four 400-mL portions of ethyl ether. The combined organic layers are washed twotimes with...
iron, manganese, nitrogen, carbon, some of them can use pure electrons, straight up. Like, if you cut the end off of an electrical cord, they could breathe it like a snorkel. (Laughter) These chemolithoautotrophs take the energy that they get ...
The best information about climate in the past comes from tests of ice many kilometers deep in Antarctica and Greenland. The tests show changes in temperature during the past four-hundred-thousand years. These tests show that levels of carbon dioxide today are the highest ever measured. These ...
We are also preparing for the next Mars Rover a tiny little experiment to make oxygen out of Mars's carbon dioxide atmosphere with an eye toward making rocket propellant and breathing air when we get to Mars. So, we are -- we are thinking and doing what we can right now, even though...
Pure Water When the water from a water source is removed from all impurities, it is called pure water or purified water. Pure water can be purified by micro-porous filtration, carbon filtration, and ultraviolet oxidation. Distilled water is the most common kind of pure water. Purification proce...
When natural gas is burnt, it provides heat energy. But a waste product alongside water is carbon dioxide, which when released into the atmosphere contributes toclimate change. Burning hydrogen does not release carbon dioxide. What's the difference between blue hydrogen and green hydrogen?
red wines: carbon dioxide is released during fermentation which causes the grape skins to rise to the surface. Winemakers must punch down or pump over the “cap” several times a day to keep the skins in contact with the juice. red wines: the grapes are pressed after fermentation is complet...
