Answer:
False
Replacement is not the molecule by molecule substitution of another mineral of different composition for the original material
Explanation:
Substitution pseudomorph a mineral that is able to replace another one after appearing in a substitution process. The volume, amount, and dimensions are the same but the element is different. This can't happen with regular elements only with substitution pseudomorphs. Substitution as a process doesn't exist. However, a phenomenon called substitution reaction exists, this process is when a functional group is replaced by another one. But not simply substitution. Therefore, the correct asnwer is false.
