During a chemical reaction, what typically happens to the chemical bonds in the reactants?
A
Bonds in the reactants are broken and new bonds are formed to create products.
B
All chemical bonds in the reactants remain unchanged.
C
Chemical bonds in the reactants are only strengthened.
D
Chemical bonds in the reactants are converted into ionic bonds.
Verified step by step guidance1
Understand that a chemical reaction involves the rearrangement of atoms, which means the bonds between atoms in the reactants must change.
Recognize that to form new substances (products), the original chemical bonds in the reactants must be broken first.
After breaking the original bonds, new bonds form between atoms to create the products of the reaction.
Note that bonds are not simply strengthened or converted into a different type without breaking; bond breaking and forming is essential for chemical change.
Summarize that the typical process in a chemical reaction is: bonds in the reactants are broken, and new bonds are formed to produce the products.
