what is the net ionic equation for NaH + H2O= NaOH +H2

NaH + HOH ==> NaOH + H2

Convert to an ionic equation.
Na^+ + H^- + HOH ==> Na^+ + OH^- + H2
Now can the ion(s) common to both sides, in this case it is the Na^+. The net ionic equation remains.
H^- + HOH ==> OH^- + H2 and you can do it up professionally if you want to add the "state" lettering.
H^-(aq) + HOH(l) ==> OH^-(aq) + H2(g)

To determine the net ionic equation for the reaction between NaH and H2O, we first need to write out the complete balanced chemical equation.

The balanced chemical equation for the reaction between NaH and H2O is:

NaH + H2O → NaOH + H2

Next, we write out the ionic equation by separating the soluble ionic compounds into their respective ions:

NaH (s) + H2O (l) → NaOH (aq) + H2 (g)

For the net ionic equation, we eliminate the spectator ions, which are the ions that appear on both sides of the equation unchanged. In this case, the H2O is a spectator ion, so it is removed.

The net ionic equation is:

NaH (s) → NaOH (aq) + H2 (g)

To determine the net ionic equation for the given reaction, we first need to write the balanced molecular equation and then break it down into its ionic components.

The balanced molecular equation for the reaction between NaH (sodium hydride) and H2O (water) is:

NaH + H2O → NaOH + H2

Next, we need to separate the soluble compounds into their respective ions, while keeping insoluble compounds in molecular form:

NaH(s) + H2O(l) → Na+(aq) + OH-(aq) + H2(g)

The sodium ion (Na+) and the hydroxide ion (OH-) are both soluble and dissociate in water. On the other hand, hydrogen gas (H2) is a product and remains in its molecular form.

Now, from the ionic equation above, we can derive the net ionic equation by removing any spectator ions, which are ions that appear on both sides of the equation and do not participate in the reaction. In this case, the sodium ion (Na+) is a spectator ion because it appears unchanged on both sides:

H2O(l) → OH-(aq) + H2(g)

Therefore, the net ionic equation for the reaction is:

H2O(l) → OH-(aq) + H2(g)
