In which of the following chemical equations, the abbreviations represent the correct states of the reactants and products involved at reaction temperature?
विकल्प
`2"H"_2("l") + "O"_2 ("l") -> 2 "H"_2"O"("g")`
`2"H"_2("g") + "O"_2("l") -> 2"H"_2"O"("l")`
`2"H"_2("g") + "O"_2("g") -> 2"H"_2"O"("l")`
`2"H"_2("g") + "O"_2("g") -> 2"H"_2"O"("g")`
उत्तर
`2"H"_2("g") + "O"_2("g") -> 2"H"_2"O"("g")`
