Save me from my failing fate and explain how to do hess' law? you will be my savior honestly i'm begging : ,)

Alright yo, I just gave this explanation off earlier

Alright dude, Hess' law isn't as complicated as most people think

Take this example
look for the change in enthalpy of  A+B-> AB

A + B -> C    enthalpy=10 kJ

C -> AB      enthalpy=10 kJ

now if you add everything together you come up with

A + B + C --> AB + C      enthalpy= 10kJ + 10 kJ= 20kJ

But notice how C is one the left and on the right of that-- so if it's on the left and on the right of the equation, you could just cancel it out

so you get A+B--> AB

tadaaa!! You found the equation you were looking for

and you know that it's enthalpy is= 10kJ + 10kJ= 20kJ

Hope that helps ya fam!

Just pm me if you need more help!
