The balanced chemical equation for the reaction between sodium and water can be represented as follows:
2Na + 2H2O → 2NaOH + H2
In this reaction, sodium (Na) reacts with water (H2O) to form sodium hydroxide (NaOH) and hydrogen gas (H2). The balanced equation shows that two moles of sodium react with two moles of water to produce two moles of sodium hydroxide and one mole of hydrogen gas.
