No information found for this chemical equation
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 K2Cr2O7 (Potassium dichromate; Potassium bichromate; Dichromic acid dipotassium salt) reacts with SO2 (sulfur dioxide) and produce H2O (water) and K2SO4 (potassium sulfate) and Cr2(SO4)3 (Chromic sulfate; Chromium(III) sulfate)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance Cr2(SO4)3 (Chromic sulfate; Chromium(III) sulfate), appearing at the end of the reaction.
Or if any of the following reactant substances SO2 (sulfur dioxide), disappearing
We no further information about this chemical reactions.
