Answer:
The correct answer is A products are formed from the reaction by breaking and forming of new bond.
Step-by-step explanation:
In a chemical reaction, reactants participate which reacts with each other to generate the product of the reaction .
Zn+H2SO4 = ZnSO4+H2
In the above reaction Zinc attacks the sulfate group of H2SO4 as e result the bond present between hydrogen atom and oxygen linked to sulfur atom undergo cleavage liberating sulfate and hydrogen molecule. This sulfate then form new covalent bond with Zinc which leads to generate ZnSO4 and H2 gas is liberated as a byproduct.
