Question

What does the following chemical equation signify ?
2Na + 2H20-2NaOH + H2​

Answer 1

Answer:

2Na + 2H20-2NaOH + 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

N

a

+

H

2

O

→

N

O

H

+

H

2

, there are

−

O

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.
