Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a scientist turns a polymer into monomers in the laboratory, would the resulting material be larger or smaller than the starting reactants?
A
larger
B
smaller
C
not enough information to answer
D
stays the same
Explanation: 

Detailed explanation-1: -The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.” Figure 3.1.

Detailed explanation-2: -Polymers are broken down into monomers via hydrolysis reactions, in which a bond is broken, or lysed, by addition of a water molecule.

Detailed explanation-3: -The monomers combine with each other via covalent bonds to form larger molecules known as polymers.

Detailed explanation-4: -When polymers are broken down into monomers, the body uses those monomers for a number of activities. Some of them include protein construction and respiration. The process of polymers breaking down to monomers is called hydrolysis.
