One benefit of this is that the weaknesses of some of their plans are covered by better plans. Another is that if the final plan doesn’t result, there are already many other ideas to go off of. A final benefit is that if the overall plan does work, it can still be easily improvised. Hope this helps! After all, this question is more opinion based.

Answer:
7.07
Explanation:
HA = weak acid = 0.053
A+ = conjugate base = 0.045
Ka = 7.2x10^-8
Ka = [H+][A-]/HA
7 2x10^-8 = [H+][0.045]/0.053
[H+] = 7.2x10^-8 x 0.053/0.045
= 8.48x10^-8
PH = -log[H+]
= -log[8.48x10^-8]
PH = -[login.48 + log10^-8]
PH = -0.928 - (-8)log10
= 7.07
