Question

Balance the following
chemical Equation
Na+H2O = NaOH + H2​

Answer 1

Answer:

2Na+2H2O=2NaOH+H2

Explanation:

Here is the answer

Answer 2

Answer:

2Na + 2H2O --> 2NaOH + H2

explanation :

In this reaction,

Na + H2O = NaOH + H

we can see that the number of nitrogen atoms is same on both sides. the number of oxygen atoms is also equal. but the number of hydrogen atom is not same in both sides of the equation. And also note that hydrogen is diatomic.

So, H becomes H2

Now to balance the entire equation out, we add 2 as a coefficient in the rest of the equation.
