Hess's Law, Chapter 8 HW

Postby VictoriaRoderick_3A » Fri Jan 08, 2016 5:52 pm

My question is in regards to the chapter 8 homework question 61.

When cancelling the out various components to the reactions, can you cancel any products from any reactants or does it have to be the continuing reaction.

For 61, can I cancel the 2NH4Br in the first and last equation?

Thank you.

Yes, you may cancel out any product and any reactant. It's the same reason why 2 + 4 + 6 = 2 + 6 + 4. It does not matter in which order you add the reactions.

Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
