### HOTDOG problem

In number 4A of the hotdog packet we didn't multiply the enthalpies by a negative when we flipped the reaction, does anyone know why? I thought we were suppose to multiply by a negative when we flipped the reaction because it's now the inverse.

Can you post the question in details?

You do flip the enthalpies when the equation is flipped. The final equation should be (2*-345kJ) + (2*21kJ) + (150kJ), where the first equation is multiplied by 2, the second equation is flipped and multiplied by 2, and the final equation is flipped as to give the final reaction 2GingerAle + 5RootBeer -> 2Vodka.
