View answer & explanation

Correct answer

Answer: (b)B.

Biomass

Why this answer is correct

The correct answer is Biomass.

Key Points

  • Biomass is a renewable energy source that comes from plants and animals.
  • Biomass contains stored chemical energy from the sun.
  • Plants produce biomass through photosynthesis.​

Additional Information

  • Biomass sources for energy include:-
  • Wood and wood processing wastes — firewood, wood pellets, and wood chips, lumber and furniture mill sawdust, and waste, etc.
  • Agricultural crops and waste materials — corn, soybeans, sugar cane, switchgrass, woody plants, and algae, and crop and food processing residues.
  • Biogenic materials in municipal solid waste — paper, cotton, and wool products, and food, yard, and wood wastes.
  • Animal manure and human sewage.
  • Fossil fuel is a fuel formed by natural processes.
  • It is natural fuel such as coal, Petroleum products, and Natural gas, that was formed millions of years ago from dead animals or plants in the ground.

Important Points

  • Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas.
  • India's Rank in Global Energy Transition Index - 74.
  • Bitumen is a low-grade of crude oil which is composed of complex, heavy hydrocarbons.
  • Asphalt, a black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid.

Key Points

Metal activity series:​

  • The metals are arranged in an activity order that is known as metal activity series.
  • The more active metals are present at the top of the series whereas the less active metals are put at the end of the series.
  • The metal activity series is as follows-

​

Importance of the series-

  • The metal activity series is used to predict displacement reactions.
  • When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed in the surface of iron and the colour of copper sulphate solution changes from blue to pale green.

Explanation:

Displacement reaction

  • It is a reaction wherein the atom or a set of atoms is displaced by another atom in a molecule.
  • The reaction shows that iron is more reactive than copper because it displaces copper from the copper sulphate solution.

Hence, Iron nails become brown whereas the solution turns green.

  • CuSO4 (aq) + Fe (s) → FeSO4 (aq) + Cu (s)
  • In this reaction following two processes take place:
  • Cu²⁺ + 2e = Cu⁰ (re­duc­tion process, Cu²⁺ is the ox­i­dizing agent)
  • Fe⁰ – 2e = Fe²⁺ (ox­i­da­tion process, Fe⁰ is the re­duc­ing agent)
  • The reaction can be double displacement reaction as well as redox reaction (oxidation and reduction both take place simultaneously).
