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 )  .

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
