Which statement correctly describes a chemical reaction?

A. Reactants come out of a reaction.
B. Energy is always released.
C. Bonds between atoms break and new bonds form.
D. Products go into a reaction.

A chemical reaction takes place when bonds between atoms of the reactants break and new bonds form in the product.
An endothermic chemical reaction requires energy to break the bonds and an exothermic reaction releases energy.
Reactants go into a reaction and products come out.
Chemical reaction:
A + B ⇒ AB
where A and B are reactants and AB is the product. Atomic bonds of A and B break to form new bonds in the product AB

The correct statement is: ** Bonds between atoms break and new bonds form. **Chemical reaction is the rearrangement of atoms to form new substances. The bonds in the reactants first break so that atoms may be free to rearrange and form new bonds resulting in the products. ;

A chemical reaction involves the breaking of bonds in reactants and the formation of new bonds in products. The correct answer is C: Bonds between atoms break and new bonds form. This process involves changes in the arrangement of atoms and can involve energy changes as well.
