Answer 1

Answer:

option (a) 2Na+2H2O===>2NaOH+H2

The reaction you are asking about is a single displacement reaction because it follows the single displacement pattern; in your example the H2O breaks up, and some (though not all) of the H is replaced by Na, forming the new compound NaOH. The remaining H atoms join to form H2 gas.

Answer 2

Answer:

2Na+2H2O→2NaOH+H2.
