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 H2O (water) reacts with Na2Se (Sodium selenide; Selenodisodium; Disodio selenide) and produce NaOH (sodium hydroxide) and H2Se (Dihydrido selenium; Dihydrogen selenide; Hydrogen selenide; Selenium hydride; Dihydridoselenium)
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance H2Se (Dihydrido selenium; Dihydrogen selenide; Hydrogen selenide; Selenium hydride; Dihydridoselenium), appearing at the end of the reaction.
Or if any of the following reactant substances Na2Se (Sodium selenide; Selenodisodium; Disodio selenide), disappearing
We no further information about this chemical reactions.

2H2O + 2NaCl → Cl2 + H2 + 2NaOH 3H2O + P2O5 → 2H3PO4 CaO + H2O → Ca(OH)2 View all equations with H2O as reactantSodium selenide; Selenodisodium; Disodio selenide
H2O + Na2Se → 2NaOH + H2Se H2O + Na2Se → NaOH + NaHSe 2HCl + Na2Se → 2NaCl + H2Se View all equations with Na2Se as reactantSodium selenide; Selenodisodium; Disodio selenide
2Na + Se → Na2Se 2Na2SeO3 → 3O2 + 2Na2Se 2Na + H2Se → H2 + Na2Se View all equations with Na2Se as productSodium selenide; Selenodisodium; Disodio selenide
2Na + Se → Na2Se 4H2 + Na2SeO4 → 4H2O + Na2Se 4C + Na2SeO4 → 4CO + Na2Se View all equations with Na2Se as productInteresting Information Only Few People Knows
