Question

Balance the following skeletal equations.

Na + Cl2 = NaCl
N2 + H2 = NH3
Na + O2 = Na20
Fe + H2O = Fe3O4 + H2
Na + H2O = NaOH + H2

Answer 1

2na+CL2 =2NaCl
N2 + 3H2= 2NH3
2NA + O2 = NA2O
3FE+4H2O=FE3O4 + 4H2
2NA + 2H2O = 2NAOH + H2

Answer 2

2Na+Cl=2NaCl
N2+3H2=2NH3
4Na+O2=2Na2O
3Fe+4H2O=2H2
2Na+2H2O=2NaOH+H2
