The compound produced when sodium peroxide is heated with excess sodium is
Answer Details
When sodium peroxide (Na2O2) is heated with excess sodium (Na) at high temperature, the resulting compound is sodium oxide (Na2O). This reaction can be represented by the following equation:
2Na2O2 + 4Na → 4Na2O
In this reaction, the excess sodium (Na) reacts with the sodium peroxide (Na2O2) to form sodium oxide (Na2O) and release oxygen gas (O2). The reaction is exothermic and produces a large amount of heat.
Sodium oxide (Na2O) is a white crystalline solid that is highly reactive with water, forming sodium hydroxide (NaOH) and releasing a large amount of heat. Therefore, it should be handled with care and stored in a dry environment to avoid contact with moisture.
In summary, heating sodium peroxide (Na2O2) with excess sodium (Na) produces sodium oxide (Na2O).
