I’m trying to do a graph on the combustion of ethanol, labelling the activation change and overall energy change, the picture is attached

Here's what I get  

Explanation:

Your graph should resemble the one below.

The ethanol and oxygen molecules must receive enough energy (perhaps from a match flame) to get over an activation energy barrier (Eₐ).

The products are lower in energy than the reactants, so the difference in energy is given off as heat (ΔH).

The overall energy change is

ΔH = Energy of products - energy of reactants

The products are lower in energy than the reactants, so the combustion of ethanol is exothermic.

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
