What occurs in a chemical reaction?
products are formed from reactants by the breaking and forming of new bonds.

a. products are formed from reactants by the breaking and forming of new bonds.

b. products are formed without chemical bonds being broken.

c. reactants are formed from products by the breaking and forming of bonds.

d. reactants are formed without chemical bonds being broken.

The correct answer is A products are formed from the reaction by breaking and forming of new bond.

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.

well we can't tell you because we cant see the time give a screen shot or something.
