Half equations:
CH2O + 2OH- ---> CH2O2 + H2O + 2e
[Ag(NH3)2]+ + e ---> Ag + 2NH3
Full equation:
CH2O + 2OH- + 2[Ag(NH3)2]+ ---> CH2O2 + H2O + 2Ag + 4NH3
The aldehyde shown is methanal. Same equation for any aldehyde, just replace CH2O with the relevant molecule and balance.

Tollens' reagent is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. Acetone is a ketone so it will not readily react with Tollens' reagent.
because
yes!!
2[Ag(NH3)2]+ + CH3CHO + 3OH- --> 2Ag + 2H2O + 4NH3 + CH3COO-

Does not react. Because Tollens' reagent only works with aldehydes. Butanone is methyl ethyl ketone (MEK).
Tollens' reagent is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. Acetone is a ketone so it will not readily react with Tollens' reagent.
The outcome of the Tollens reagent reacting with methanal (formaldehyde), ethanol (ethyl alcohol), and propanone (acetone) is the formation of metallic silver (Ag) in the case of methanal, while ethanol and propanone do not show a significant reaction with Tollens reagent. Tollens reagent is used as a chemical test to distinguish between aldehydes and ketones, where aldehydes react to produce a silver mirror, while ketones do not react.

yes!!

tollen reagent
Pyrrole-2-aldehyde does not respond to Tollens reagent because it is not a reducing sugar. Tollens reagent (silver nitrate) is used to test for the presence of aldehyde groups, which are commonly found in reducing sugars. Reducing sugars contain aldehyde groups and are capable of donating electrons to Tollens reagent, forming a silver mirror on the test tube wall. Pyrrole-2-aldehyde does not contain aldehyde groups, and therefore is not a reducing sugar. As a result, it does not react with Tollens reagent.
2[Ag(NH3)2]OH is tollen's reagent
no negative
