Consider the decomposition equilibrium for dinitrogen pentoxide: at a certain temperature and a total pressure of 1.00 atm, the n2o5 is 0.50% decomposed (by moles) at equilibrium.
(a). if the volume is increased by a factor of 10.0, will the mole percent of n2o5 decomposed at equilibrium be greater than, less than, or equal to 0.50%. explain.
(b) calculate the mole percent of n2o5 that will be decomposed at equilibrium if the volume is increased by a factor of 10.02n2o5(g) > 4no2 (g) + o2 (g)

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

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.
