When heated, potassium chlorate (KClO 3) decomposes into solid potassium chloride (KCl) and oxygen gas (O 2).What amount of oxygen is produced from the decomposition of 3.30 mol of potassium chlorate? Carbon monoxide reacts with oxygen to form carbon dioxide according to the equation: \[2 \ce{CO} \left( g \right) + \ce{O_2} \left( g \right) \rightarrow 2 \ce{CO_2} \left( g \right) \nonumber \].

The ferrozine method revisited: Fe(II)/Fe(III) determination in natural waters. _____Fe 2 O 3 (s) + _____Cl 2 (g) _____FeCl 3 (s) + _____O 2 (g) Sodium metal reacts with ammonia to give sodium amide and hydrogen gas, according to the equation shown below; balance this equation. Tosca, N.J.; Knoll, A.H. Juvenile chemical sediments and the long term persistence of water at the surface of Mars. This is then oxidised by warming it with hydrogen peroxide solution. To predict the products, we need to know that aluminum will replace iron and form aluminum oxide (the metal will replace the metal ion in the compound). Ionic strength is a barrier to the habitability of Mars. Jarosite and hematite at Meridiani Planum from Opportunitys Mossbauer spectrometer. Hong, C.C. ; Franz, H.B.
