4. Sodium reacts with water to form sodium hydroxide and hydrogen gas. The balanced equation which represents the above reaction is

• Na(s) + 2H20(l) → 2NaOH(aq) + 2H2(g)
• 2Na(s) + 2H2O(l) → 2NaOH(aq) +H2(g)
• 2Na(s) + 2H20(l) → NaOH(aq) + 2H2(g)
• 2Na(s) + H20(l) - 2NaOH(aq) + 2H2(g)

The correct answer is 2Na(s) + 2H2O(l) → 2NaOH(aq) +H2(g)
