Question

oxygen and hydrogen and react with an explosion to form water when they are mixed together and ignited with a spark which of the following potential energy diagrams best represent this reaction?

Answer 1

where are the diagrams

Answer 2

They're in the attachment

Answer 3

there is nothing attached

Answer 4

There should've been but here

Answer 5

i think it may be C because the reaction is exothermic meaning it gives off heat
