Plywood and particle board are often glued with cheap, waterproof urea-formaldehyde resins. Two to three moles of formaldehyde are mixed with one mole of urea and a little ammonia as a basic catalyst. The reaction is allowed to proceed until the mixture becomes syrupy, and then it is applied to the wood surface. The wood surfaces are held together under heat and pressure, while polymerization continues and cross-linking takes place. Propose a mechanism for the base-catalyzed condensation of urea with formaldehyde to give a linear polymer, and then show how further condensation leads to cross-linking.

With regards to this, I have been reading journals about activated carbon that is being modified. Now, the activated carbon is modified through acid treatment, and sulfuric acid is added to it. The result was, that there is a presence of SO3-, C=O=C, and C=O on the modified activated carbon. They concluded that the process of sulfonation on the activated carbon treated with sulfuric acid took place. Can you explain the chemistry/mechanism/reaction that happened? Explain in detail and clearly. Thank you so much!
