Look at this equation. CH 4 ( g ) + 2 O 2 g → CO 2 g + 2 H 2 O g . Which one of the following statements is completely correct?

four C − H bonds and two O = O bonds are broken (endothermic) and two C = O bonds and four O − H bonds are formed (exothermic).

four C - H bonds and two O = O bonds are broken (exothermic) reaction and two C = O bonds and four O - H bonds are formed (endothermic).

four C − H bonds and two O - O bonds are broken (endothermic) and two C - O bonds and four O − H bonds are formed (exothermic).

four C − H bonds and two O = O bonds are broken (endothermic) and two C = O bonds and two O − H bonds are formed (exothermic).
