Question

cuo+h2. cu+h2o उक्त अभिक्रिया में उपचनित व अचयनित पदार्थ का नाम कारण सहित बताइए​

Answer 1

Answer:

कॉपर ऑक्साइड कॉपर में अपचयित हो रहा है। इस अभिक्रिया में हाइड्रोजन (H2), H2O में परिवर्तित हो रही है। अर्थात ऑक्सीजन का हाइड्रोजन H2 के साथ संयोग हो रहा है।

Answer 2

Copper oxide is reduced while hydrogen is oxidized.

• In the redox reaction: CuO +H₂ ⟶Cu+ H₂ O ;

1. H₂ is a result of losing electrons, whereas Cu is reduced because of receiving electrons.
2. In cupric oxide, copper in the +2 oxidation state gains two electrons and is reduced to the 0 states in a copper atom.
3. In water, hydrogen in the 0 states of an atom loses two electrons and is oxidized to the +1 state.
4. As a consequence, copper oxide is reduced while hydrogen is oxidized.
5. Thus, copper oxide is an oxidizing agent and hydrogen is a reducing agent.

• Redox processes offer a wide variety of applications in electrochemistry. The redox process creates electrical energy by the battery that generates DC.
• Storage cells, which provide all of a vehicle's electrical needs, are also redox-dependent.
• Photosynthesis is a redox reaction because carbon dioxide reduces to carbohydrates, and water oxidizes to oxygen.
