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 Na (sodium) reacts with Se (Selenium; C.I.77805; Se) and produce Na2Se (Sodium selenide; Selenodisodium; Disodio selenide)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance Na2Se (Sodium selenide; Selenodisodium; Disodio selenide), appearing at the end of the reaction.
Or if any of the following reactant substances Se (Selenium; C.I.77805; Se), disappearing
We no further information about this chemical reactions.
sodiumCl2 + 2Na → 2NaCl 2H2O + 2Na → H2 + 2NaOH Na + C2H5COOH → H2 + C2H5COONa View all equations with Na as reactant
Selenium; C.I.77805; SeO2 + Se → SeO2 2Na + Se → Na2Se H2 + Se → H2Se View all equations with Se as reactant
