Question

Balance the following
equation Nat H₂o -) Na OH + H₂​

Answer 1

Answer:

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

explanation:

the number of hydrogen atoms was not the same in both sides of the equation.

because of that, we put 2 as a coefficient of H2O.

After that, to balance out the whole equation, we added 2 as a coefficient in Na and NaOH as well.

like this we get a balanced equation ;

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

Answer 2

Answer:

Sodium reacts with cold water and gives sodium hydroxide and hydrogen gas. The balanced chemical equation is

2Na+2H

2

O→2NaOH+H
