when 0.20 m nh4cl (aq) and 0.20 m naoh(aq) are mixed, the reaction represented by the equation above occurs and a strong smell of ammonia, nh3 is observed. based on this information, which of the following statements is true? And Why??

b ) NH₄⁺ is a stronger acid than H₂O ( l )

Explanation:

NH₄⁺ + OH⁻ = NH₃ + H₂O .

NH₄⁺ is a conjugate acid of NH₃

OH⁻ is a conjugate base of H₂O .

NH₄⁺ is capable of giving H⁺ to OH⁻ to produce H₂O so it is stronger acid than H₂O .

Had H₂O been stronger , it would have given H⁺ to NH₃ to produce NH₄⁺ but it does not happen .

So NH₄⁺ is a stronger acid than H₂O ( l )  .

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
