Any student is welcome to use this for extra practice and anyone is welcomed to amswed the question. Here is a couple of practice problems

a) 2 N2O(g) + O2(g)  4 NO(g)

B) H2(g) + CO2(g)  H2O(g) + CO(g)

C) 4 HCl(g) + O2(g)  2 Cl2(g) + 2 H2O(g)

d) 3 H2(g) + N2(g)  2 NH3(g)

e) H2(g) + Cl2(g)  2HCl(g)

f) 2 SO2(g) + O2(g)  2 SO3(g)
