  4. Atomic energy plant

Show answer
Correct Option: C
Explanation:

Geothermal energy plant is located in the Parvati valley near Manikarn in Himachal Pradesh.
Geothermal power plant (flash steam, combined cycle) in Iceland. Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy). They essentially work the same as a coal or nuclear power plant, the main difference being the heat source.

  1. Shortage of hydro-electricity

  2. Malnutrition leading to short supply of energy in the human body

  3. Shortage of the thermal power

  4. Impending danger of total exhaustion of fossil fuels like coal and petroleum

Show answer
Correct Option: D
Explanation:

An energy crisis is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular those that supply national electricity grids or those used as fuel in vehicles.

The overall reaction of a hydrogen-oxygen fuel cell is:

chemistry energy fuel cell fuel cells electrochemistry, rechargeable batteries, and fuel cells

  1. $2H _{2(g)}+O _{2(g)}\rightarrow 2H _2O _{(l)}$

  2. $2H _{2(g)}+4OH^- _{(aq)}\rightarrow 4H _2O _{(l)}+4e^-$

  3. $O _{2(g)}+2H _2O _{(l)}+4e^-\rightarrow 4OH^- _{(aq)}$

  4. $4OH^- _{(aq)}+4e^-\rightarrow 2H _2O _{(l)}$

Show answer
Correct Option: A
Explanation:
A fuel cell is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuelwith oxygen or anotheroxidizing agent.
The reactions which takes place in hydrogen-oxygen fuel cell are,
At cathode:$2H _{2(g)}+4OH^{-} _{(aq)}\rightarrow 4H _2O _{(l)}+4e^{-}$
At cathode:$O _{2(g)}+2H _2O _{(l)}+4e^{-}\rightarrow 4OH^{-} _{(aq)}$
Overall reaction: $2H _{2(g)}+O _{2(g)}\rightarrow 2H _2O _{(l)}$
