Aquated ammonium ions (NH4+) are weakly acidic, with Ka= 5.5 x 10^(-10) at 25 degrees Celsius. NH4+ (aq) + H2O (l) <---> NH3 (aq) + H3O+ (aq)

What is the pH of a 1.00 mol/L solution of ammonium nitrate (NH4NO3)?

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

it is a solid

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.
