reacting one mole of oxygen (O2) absorbs 445 kJ of energy

 reacting one mole of oxygen (O2) releases 445 kJ of energy

 reacting one mole of methane (CH4) absorbs 890 kJ of energy

 reacting two moles of methane (CH4) releases 890 kJ of energy

nincompoop · Answer

the terms we have look at now here are endothermic and exothermic reactions 
endothermic reaction absorbs heat 
exothermic gives (release) off heat 
the minus and plus sign in energy dictate if it is an endo or exo 
endo + 
exo -

Would it be exo because of the result? Also the link doesn't work for me.

WAIT it will be D because it's releases 890 kj of energy right?
