Пояснення:

2 Na + 2 H2O = 2 NaOH + H2

Answer 2

The reaction of sodium (Na) with water (H2O) is a highly exothermic and potentially dangerous chemical reaction. When sodium comes into contact with water, it reacts vigorously to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The balanced chemical equation for this reaction is as follows:

2Na + 2H2O → 2NaOH + H2

In this reaction:

• Sodium (Na) atoms lose electrons to form sodium ions (Na⁺).
• Water molecules (H2O) are broken down into hydroxide ions (OH⁻) and hydrogen ions (H⁺).
• Sodium ions (Na⁺) react with hydroxide ions (OH⁻) to form sodium hydroxide (NaOH).
• Hydrogen ions (H⁺) react with each other to form hydrogen gas (H2).

The reaction is highly exothermic because it releases a large amount of heat energy. Additionally, the formation of hydrogen gas can lead to the production of a flammable gas, which can result in a fire or explosion if not handled properly. Therefore, the reaction of sodium with water should only be carried out by trained individuals in a controlled environment and with appropriate safety precautions in place.
