How to draw the potential energy diagram for “N2(g+O2(g)→2NO(g)△H=+182.6kJ”

I need help asap!!Please and thank you all;）

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass

An electron moved from shell n = 2 to shell n = 1. what most likely happened during the transition? a fraction of a photon was added. a photon of energy was absorbed. a fraction of a photon was removed. a photon of energy was released.

1) describe the physical layout of the ocean floor ? 2) explain how the dumbo octopus swims differently than other octopus species and why this would be an advantage in the aphonic zone . 3) why are the types of organisms that live at each underwater hot vent so dramatically different ?
