Answer-4)
There are basically 4 types of chemical weathering. Which includes hydrolysis, oxidation, carbonation and hydration.
Hydrolysis is a kind of chemical breakdown of a particular substance when it is combined with water.
Note :- As per HomeworkLib policy i am allowed to answer only the first question.
Hope this helps you !!!

bond formation is illustrated as Path A. An alternative
pathway for this process has been proposed as well, illustrated in
Path B. In this alternative pathway, a second molecule of
acid 1 out-competes the amine 4
for the pivotal activated acyl derivative 3,
leading to a transient symmetrical anhydride
7(with discharge of 6). In Path
B, anhydride 7 then is the active electrophile
that reacts with amine 4 to give the observed
