You will now learn on how to determine a reaction is endothermic and exothermic. so sit back and enjoy your brain complexity okay? Cheers!

In order for the reactants to form a new compound(products), they need to break is it??

In order to form a new compound here on the product side, the reactant that gained energy on Bond Breaking needs to release energy.. so far so good students?

EXAMPLE  CALCULATION OF TOTAL NET ENERGY.

Energy In (ENDOTHERMIC) Hydrogen gas and chlorine gas will break

Energy In (EXOTHERMIC)
Hydrogen and Chlorine both lose energy to combine together and form Hydrogen chloride.

Steps to draw energy level diagram:

1. Determine your reaction either it is exothermic or endothermic (refer to your calculation)

2. If exothermic, draw the line for reactants above products. Vice versa for endothermic.

3. Write the reactants and products.

4. Write the Total Net Energy.

Given the table of energy for each bond (Don't afraid you don't have to "hafal") LOL

Now, try to draw the energy level diagram when Hydrogen reacts with oxygen to produce water and PROUDLY, SHARE YOUR ASNWER! yeayyyy!

TIPS!
You need to do the calculation first tau! hehe
