Given steps 1-3, determine the H_r for net reaction below.

Step 1: 2 C_(s) + O_2(g) 2 CO_(g) ||||||||||||||||||||||||||||||||| H_r = -393.5 kJ/mol

Step 2: S_(s) + O_2(g) SO_2(g) ||||||||||||||||||||||||||||||||||||| H_r = -296.1 kJ/mol

Step 3: CS_2(l) + O3 _2(g) CO_2(g) + 2 SO_2(g) |||||||||||| H_r = -1072 kJ/mol Net Reaction: 2 C_(s) + 2 S_(s) CS_(l) NOTE: (I used the "||||||" to space the data to the side, it does not represent numerical information whatsoever.) Some guidance to solve this would be lovely! Thank you so much. Any tips you have would be greatly appreciated.
