The following chemical equation shows the reaction in which
natural gas (methane or CH4) is burned.
Refer to this equation while answering the following questions.
18. Refer to the equation above. The continued use of this
reaction by humans may contribute to
a) acid rain
b) increased rates of skin cancer.
c) increases in average annual temperatures worldwide.
