2H2(g) + O2(g) = 2H2O(g) A chemist mixes 2.56 L of hydrogen gas with excess oxygen gas at STP. When the reaction is complete and STP is restored, how many liters of water vapor will be present?

58750.08068 is the answer i think

elements make up everything, and they combine to make compounds.

the answer is c

the answer is true. hope it .

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
