2. Na(s) +
Cl2(g) ! NaCl(s)
3. CO2(s) ! CO2(g)
4. SO2(g) +
O2(g) ! SO3(g)
5. 2 H2(g) + O2(g) ! 2 H2O(`)

1 is not.
2 is if you have 1/2 Cl2(g)
3. I don't understand the 2 but I think this is not because for Co I would write Co and not Co2.
4 is if you write 1/2 O2(g)
5 is not. You can make it one by
H2(g) + 1/2 O2(g) ==> H2O(g)
