Question

During the combustion of methane (CH4) with oxygen (O2), energy is released, as carbon dioxide (CO2) and water (H2O) form. How would an energy graph for this reaction look?

Answer 1

A. The energy of carbon dioxide and water would be higher than the energy of methane and oxygen in this endothermic reaction.
B. The energy of methane and oxygen would be higher than the energy of carbon dioxide and water in this exothermic reaction.
C. The energy of methane and oxygen would be higher than the energy of carbon dioxide and water in this endothermic reaction.
D. The energy of carbon dioxide and water would be higher than the energy of methane and oxygen in this exothermic reaction.

Answer 3

knowing that energy is released in the process, what do you think?

Answer 4

A right?

Answer 5

nope, energy is given off. this energy comes from methane + oxygen.. the energy of the system decreases

Answer 6

ohhh so its B? @aaronq

Answer 7

yesss
