Chemistry Help
Hi, I'm having trouble with these problems if anyone could write step by step how to do them on paper and send me a picture that would be nice! Much Appreciated.

ShammyShakes pretty much got down the most of what is needed to approach this problem. Anyway, since you wanted a picture of the steps, please refer to the link. (what I did during class ) http://imgur.com/9nLLmoA
Pretty much what @ShammyShakes said. However, multiplying each equation will not double the change in enthalpy; enthalpy increases by a factor equal to the coefficient of multiplication.
It's like a puzzle. You're allowed to multiply coefficients (which also doubles the deltaH), reverse reactions (changes the sign of deltaH) and then add two reactions together (get rid of intermediates-compounds that appear on both the left and right side). It's a fairly simple problem that just requires rearranging of the two given equations.
