Answer 2

The sequence you provided represents a series of chemical reactions involving sodium (Na) and other compounds. Let's break it down step by step:

1. Na (sodium) → NaH: In this step, sodium reacts with hydrogen gas (H2) to form sodium hydride (NaH). The balanced chemical equation for this reaction is: 2 Na + H2 → 2 NaH

2. NaH (sodium hydride) → NaOH (sodium hydroxide): Sodium hydride reacts with water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The balanced chemical equation for this reaction is: NaH + H2O → NaOH + H2

3. NaOH (sodium hydroxide) → NaNO3 (sodium nitrate): In this step, sodium hydroxide reacts with nitric acid (HNO3) to form sodium nitrate (NaNO3) and water (H2O). The balanced chemical equation for this reaction is: NaOH + HNO3 → NaNO3 + H2O

So, the overall sequence of reactions is: Na + H2 → NaH NaH + H2O → NaOH + H2 NaOH + HNO3 → NaNO3 + H2O
