The reaction of calcium and zinc carbonate yields calcium carbonate and zinc. To balance, we should remember that the number of atoms of each element in the reactants and products side should be equal. The balanced chemical reaction is written as follows:
Ca + ZnCO3 = CaCO3 + Zn
Answer:
Substrate D
Explanation:
In substitution reactions the tertiary substrates cannot undergo substitution via neighboring group participation (NGP) due to the steric impediment, this means that the volume occupied by the substituents is very large and makes it impossible to attack the nucleophile to the substrate carbon.
