Define H2SO4. H2SO4 synonyms, H2SO4 pronunciation, H2SO4 translation, English dictionary definition of H2SO4. n. A highly corrosive, dense, oily liquid, H2SO4, colorless to dark brown depending on its purity and used to manufacture a wide variety of chem
当硫酸(H2SO4)与硫化氢(H2S)发生反应时,观测到双重置换反应。 代表这种反应的化学方程式如下: H2SO4 + H2S → 2H2O + 3S。 So, in this reaction, when sulfuric acid (H2SO4) mixes it up with hydrogen sulfide (H2S), they end up making some water (H2O) and sulfur (S). It's like the su...
Electrolysis is a process that uses electricity to drive a chemical reaction. In the electrolysis of water, an electric current is passed through water, causing it to split into hydrogen and oxygen gases. The overall reaction is: 2H2O(l) -> 2H2(g)+ O2(g)。 Electrodes and Electrolytes. ...

Balance the reaction of H2SO4 + HNO3 + C3H5(OH)3 = C3H5N3O9 + H2SO4 + H2O using this chemical equation balancer!
虽然 conc. H2SO4 是 oxidizing agent，但 HCl is very weak reducing agent，conc. H2SO4 唔够强去进行 redox reaction。 Conc. H2SO4 一来吸水，二来唔会 react with HCl，所以 can be used to dry HCl(g). = 的确HCl 会dissolve in water 成为hydrochloric acid 不过既然有Conc. ...
To calculate the limiting reagent, enter an equation of a chemical reaction and press the Start button. The reactants and products, along with their coefficients will appear above. Enter any known value for each reactant. The limiting reagent will be highlighted in red. Theoretical yields of ...
of gypsum to anhydrite were explored.The results show that increasing reaction temperature,sulfuric acid concentration and reaction time are beneficial to the transformation of gypsum to anhydrite.When gypsum is converted to anhydrite,the anhydrite do not change after prolonging the reaction time.When ...
