A gardener maintains the plants inside the zoo pavillions. If he spills lime that is used to increase pH of soil into a wet walkway and it starts to bubble. A salt and water are produced. Which type of chemical reaction is this (like Synthesis, Decompositioin, Single Displacement or Double displacement)? With whom did the lime react ? [

Double-replacement.
But also-
Neutralization. Its basically a titration of the acids in the dirt and the base of the lime.
