Final answer:
When 100,000,000 pounds of sodium fall in water, a violent reaction occurs, producing heat, hydrogen gas, and sodium hydroxide.
Step-by-step explanation:
When 100,000,000 pounds of sodium fall in water, a violent reaction would occur. This reaction would produce heat, hydrogen gas, and sodium hydroxide. Sodium is a highly reactive metal that reacts vigorously with water to form sodium hydroxide and hydrogen gas. The reaction is represented by the equation 2Na (s) + 2H₂O (l) → 2NaOH (aq) + H₂ (g).
