Please help with both questions and label everything. If hand written response please make it as legible as possible. I will up vote :)

1) Please show the mechanism for the formation of the acetal product in the following acid catalyzed reaction. (Hint: Protonation of the carbonyl group starts the process.) Which parts of the mechanism are similar to SN1,SN2,E1, or E2 mechanisms? 2) When conjugated aldehydes or ketones are attacked by a nucleophile, often more than one product forms. Please show resonance structures to explain which positions in the following conjugated ketone can react with NaBH4. Which product(s) can form
