Temperature: 300 - 500°C Catalyst: mixture of CuSO4
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 CuS (copper(ii) sulfide) reacts with O2 (oxygen) and produce CuO (copper(ii) oxide) and SO2 (sulfur dioxide)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance SO2 (sulfur dioxide), appearing at the end of the reaction.
Or if any of the following reactant substances O2 (oxygen), disappearing
We no further information about this chemical reactions.
copper(ii) sulfide
3CuS + 8HNO3 → 3Cu(NO3)2 + 4H2O + 2NO + 3S CuS + 10HNO3 → Cu(NO3)2 + 4H2O + H2SO4 + 8NO2 2CuS + 3O2 → 2CuO + 2SO2 View all equations with CuS as reactantoxygen
2Mg + O2 → 2MgO 2H2S + 3O2 → 2H2O + 2SO2 2CO + O2 → 2CO2 View all equations with O2 as reactantoxygen
2H2O → 2H2 + O2 2KNO3 → 2KNO2 + O2 2AgNO3 → 2Ag + 2NO2 + O2 View all equations with O2 as productoxygen
2AgNO3 → 2Ag + 2NO2 + O2 2Cu(NO3)2 → 2CuO + 4NO2 + O2 2H2O → 2H2 + O2 View all equations with O2 as productInteresting Information Only Few People Knows
