Answer 1

Answer:

1.                                 2Na + 3H2O ->2NaOH+H2

The correct equation is:

                                2Na + 2H2O -> 2NaOH + H2

2.                                  4P + 4O2 -> 2P2O5

The correct equation is:

                                    4P + 5O2 -> 2P2O5

3.                              Fe2O3 + 2H2- >2Fe+3H2O.

The correct equation is:

                                 Fe2O3 + 3H2 -> 2Fe+3H2O.
