In zero gravity no convection occurs, that normally shapes the flame, disperses CO2 and brings fresh air to the wick. Without convection, CO2 from combustion does not disperse as readily and tends to smother the flameWhat color is octopus blood?Blue. Both squids and octopuses have blue blood. They use an oxygen-carrying molecule in their blood called hemocyanin that contains copper. In cold conditions with low oxygen pressure, hemocyanin oxygen transportation is more efficient than hemoglobin oxygen transportation.What is the main difference between Coca-Cola sold in the US, and the Coca-Cola sold in the EU?Sugar. In the United States, Coca-Cola uses high-fructose corn syrup instead of sugar (sacharose) as its main sweetener. There is a small production of sugar-based "Kosher for Passover" Coca-Cola, as Ashkenazi Jews do not consume high fructose corn syrup during Passover.What does synthesis gas (water gas) consist of?Carbon monoxide (CO) and hydrogen (H2). Water gas is a mixture of carbon monoxide and hydrogen produced from synthesis gas. Synthesis gas is a useful product, but requires careful handling due to its flammability and the risk of carbon monoxide poisoning. The water-gas shift reaction can be used to reduce the carbon monoxide while producing additional hydrogen, resulting in water gas.
