Question

Na +H2O = ____________+_______________

Answer 1

Answer:

Heya mate.....

Na + H2O ----> Na2O + H2

Hope it helps.....

Answer 2

Answer:

2Na+2H2O→2NaOH+H2

Explanation:

You have to count the number of atoms in both sides of the reaction to be equal, to make it a little easier you can make a list. So in the equation

Na+H2O→NaOH+H2 , there are

1−Na−1

2−H−3

1−O−1

So you multiply NaOH and H2O by 2, so you have 4 hydrogens in both sides, and then multiply Na by 2 to be equal to the NaOH you previously multiplied.
