Sodium reacts vigorously with water to produce
Sodium chloride (NaCl) and oxygen gas (O2)
Sodium nitrate (NaNO3) and water (H2O)
Sodium hydroxide (NaOH) and hydrogen gas (H2)
Sodium oxide (Na2O) and hydrogen gas (H2)
Explanation
When sodium reacts with water, it undergoes a highly exothermic reaction, producing sodium hydroxide (NaOH) and hydrogen gas (H2).
