Many household cleaning products contain oxalic acid, h2c2o4, a diprotic acid with the following dissociation constants: ka1=5.9×10−2, ka2=6.4×10−5. part a calculate the equilibrium concentration of h3o+ in a 0.20 m solution of oxalic acid. express your answer to two significant figures and include the appropriate units.

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

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.
