What is a word equation for the reaction of sodium and water?

Sodium reacts exothermically with water. When it reacts small pea-sized pieces will bounce across the surface of the water until they are consumed by it, whereas large pieces will explode. While sodium reacts with water at room temperature, the sodium piece melts with the heat of the reaction to form a sphere, if the reacting sodium piece is large enough. The reaction with water produces very caustic sodium hydroxide and highly flammable hydrogen gas.
