11) Nitrogen oxides undergo many interesting reactions in the environment and in industry. Given the following information, calculate H for the overall equation:
2 NO2(g) + 1/2 O2(g) N2O5(s).
N2O5(s) 2 NO(g) + 3/2 O2(g), deltaH = 223.7 kJ
NO2(g) NO(g) + 1/2 O2(g), delataH = 57.1 kJ
delataH = kJ
12Write all coefficients, even if they are fractions or 1.)
(a) (Apply fractions as needed.)
(s) + (g) 5 NaCl(s)
(b) (Use the lowest possible coefficients.)
(s) + (g) CaCl2(s)
(c) (Apply fractions as needed.)
(g) O3(g)
(d) (Apply fractions as needed.)
Mg(s) + (s) + (g) Mg3(PO4)2(s)
