use standard enthalpies of formation to calculate delta Hrxn for the following reaction. 2H2S(g)+3O2(g)-->2H2O(l)+2SO2(g) express the answer using four significant figures

Question

Delta Hrxn = ? kJ

Answer 1

DHfrxn = (n*DHf products)-(n*DHf reactants)
Look up DHf values in your text or notes.

Answer 2

we dnt take notes that's why im so lost

Answer 3

Then look in your text. Most texts have a set of delta H^o_f values.

Answer 4

And I might suggest you take notes. You can't possibly remember everything.

Answer 5

honestly all we do is labs during class i would love to take notes

Answer 6

Do you have a table in your text? I may be able to find a table on the web or I can look up some values if your text doesn't have them listed.
