Explanation: The ideal environmental conditions for a reaction, such as temperature, pressure, catalysts, and solvent. Catalysts are substances that speed up the pace (velocity) of a chemical reaction without being consumed or becoming part of the end product. Catalysts have no effect on equilibrium situations.
In a full sentence, you can also say H2SO4 (sulfuric acid) reacts with HI (hydroiodic acid) and produce H2O (water) and H2S (hydrogen sulfide) and I2 (iodine)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance I2 (iodine), appearing at the end of the reaction.
Or if any of the following reactant substances HI (hydroiodic acid), disappearing
We no further information about this chemical reactions.
sulfuric acidH2SO4 + Na2SO3 → H2O + Na2SO4 + SO2 10FeO + 18H2SO4 + 2KMnO4 → 5Fe2(SO4)3 + 18H2O + 2MnSO4 + K2SO4 Cu + 2H2SO4 → 2H2O + SO2 + CuSO4 View all equations with H2SO4 as reactant
hydroiodic acid2HI → H2 + I2 4HI + O2 → 2H2O + 2I2 Cl2 + 2HI → 2HCl + I2 View all equations with HI as reactant
hydroiodic acidH2 + I2 → 2HI 2H2O + CaI2 → Ca(OH)2 + 2HI H2S + I2 → 2HI + S View all equations with HI as product
