Answer 1

Most chemical reactions involve both the breaking and making of chemical bonds. ... This reaction involves the breaking of the four carbon-hydrogen bonds in methane and the oxygen-oxygen bond in O2. New bonds formed are the two carbon-oxygen bonds (in CO2) and hydrogen-oxygen bonds (in H2O).

Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products!
