Question

Na+H2ONaOH+H2 balance it hit and trail method

Answer 1

Answer:

2 N a + 2 H 2 O → 2 Na O H + H 2

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  

N a + H 2 O → N a O H + H 2

, there are

1− N a − 1 2− H − 3

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.
