She has previously written for Science News, Wired, The Santa Cruz Sentinel, the radio show Big Picture Science and other places. The greater outside pressure causes the balloon to inflate in an inverted manner. N2 + 3H2 2 NH3. But, it was thought that the planet's oxygen (O2) formed from two oxygen atoms colliding and combining on some surface, not because the oxygen molecules split from carbon dioxide (CO2), Ng said. An oxide is a compound containing both the element and oxygen chemically combined together. Oxygen gas, generated by the reaction 2KClO3 (s)---2KCl (s)+3O2 (g), is collected over water at 27C in 3.72L vassel at a total pressure of 730 torr.
