    For my chemistry homework we have been tasked with completing an energy diagram for the burning of methane ( CH4 + 2O2 --> CO2 + 2H2O ) using this diagram attached. We have learnt the basics of energy diagrams at school ( energy goes up when bonds are broke and energy goes down where bonds are made ), but I don't understand the placement of the lines of the diagram. Could someone please explain to me what the diagram means and how to complete it. Thanks

    drew it to best of my ability
    key idea is that more energy is needed to make bonds than break bonds, so it's negative energy change and so exothermic

    No idea what the other line is suppose to be lol
    Anything else just DM me
