The tail gas discharged from automobiles can first pass through a small jar filled with clean water and aluminum powder, a small jar filled with palladium dichloride and sodium hypochlorite solution, and then a corrosion-resistant jar filled with barium hydroxide solution, and then the purified tail gas (containing a part of hydrogen and CrbOxg2) after impurity removal gas treatment can be catalyzed into? Methanol.
hydrogen and oxygen can be obtained by adding sulfur dioxide SllO2 and aluminum AL powder into water H2O, and adding calcium dihydrogen and calcium peroxide. Geological geography \ to escape the earthquake disaster, stretch the torch to measure oxygen, and boil at high pressure. 2. hydrogen, calcium oxide, calcium oxide ..
About making friends: Li+Lei = Li? Ray, Ray+Lee = Lee? Ray, Lee? Lei Shi and Li++Lei|| can be mentioned in the text. Making friends = compound reaction, don't break friends = decomposition reaction, changing friends = displacement reaction, and changing one of two friends = double decomposition reaction. About the landform of stone, the landform of calcified stone, the landform of lava and stalagmite. Ancient transportation routes: Silk Road, Salt Road, Tea Horse Road, Oil Salt Road. PdCl?

triangle chain of calcium carbonate, bidirectional cycle, triangle chain of copper oxide, five-step cycle, rust cycle of iron oxide water. The cycle of sodium peroxide and carbohydrate, carbon hypochlorite? Water circulation.
sulfur dioxide SLO? 2? Introducing it into clear lime water, which is firstly caused by Ca(OH)2? +SLO? 2? ==CaSO3+H2O, and then because of 2CaSO3+ gas O? 2==2CaSO4 is dissolved into water by pore oxidation, or because CaSLO3+H2O+SLO2==Ca(HSLO? 3)2, again? When sulfur water SLf is combined and dissolved in water, the clarified lime water will become turbid in an instant. When chlorine gas is introduced into the aqueous solution of sulfur dioxide, it will first react with water H? O reacts to generate HCLO hypochlorite, and then reacts with sulfur dioxide. Hydrochloric acid and sulfuric acid are generated.
The rivers and lakes of the motherland are all people: the rivers and lakes of the motherland can be compared with nannies, just like a person. The Yellow River only stretches out hard arms, and the Yangtze River is sweet milk to feed and nourish everything. Heilongjiang is a faucet spouting, Dongting Lake is the liver in the milk-Yangtze River, the lake of Thousand Islands and the lake of Mabian Yongcuo are two eyes in the eyes. The Pearl River is just a great artery in the lower part.
The Beijing-Hangzhou Grand Canal is the blood of the motherland and China. It transports fresh blood and runs through the whole body. Taihu Lake in the Middle East, the small center under the milk, Poyang Lake, is a turning point of milk pipeline. Chaohu Lake, look at this name, it really looks like a belly of a person. The rivers and lakes of the motherland are really like one person.
on cloudy and rainy days with thunder and lightning (production and discharge), will it happen at high altitude? Smelly Oxygen ox g3? And nitric oxide, nitric acid rain.
chlorine? Gas, charcoal and water react to produce carbon dioxide and hydrogen chloride. Wet? Palladium chloride in water? Hydrogen chloride and carbon dioxide are also produced after reacting with carbon monoxide.
use equation ① to balance the quality coefficients? Method and (2) how to find the original number ratio of quality factors? Method, to infer the chemical formula of organic matter before the reaction. Balance system method and mass ratio method.
