In this chemical reaction, the reactants are methane (CH 4 ) and oxygen (O 2 ), and the products are carbon dioxide (CO 2 ) and water (H 2 O). A chemical reaction involves the breaking and forming of chemical bonds. When methane burns, bonds break in the methane and oxygen molecules, and new bonds form in the molecules of carbon dioxide and water. Q: Burning of methane is a type of what, which involves the breaking and forming of bonds? Choices: - liquid reaction - physical reaction - toxic reaction - chemical reaction A:
Answer:
chemical reaction
