Apiece of limestone erodes due to acid rain. this process can be best described as

a. slow chemical change.
b. rapid chemical change.
c. slow physical change.
d. rapid physical change

The correct option is a.

Explanation: Limestone is a mineral having chemical formula . When it is reacted with acid, it forms a new substance and hence, this reaction is considered as a chemical reaction.

The rocks does not dissolve in the acid easily and therefore this reaction is considered as a slow chemical reaction.

i believe it is a.) released into

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
