For the reaction: no(g) 1/2 o2(g) →→ no2(g) δδh°rxn is -114. 14 kj/mol. Calculate δδh°f of gaseous nitrogen monoxide, given that δδh°f of no2(g) is 33. 90 kj/mol.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
