The amount of coal burnt each year to produce 8.53 × 10¹⁶ Joule of energy is 2.3 x 10¹² gram.
What is Combustion?
Burning of coal in the presence of air is called combustion.
As according to the given question,
A coal-burning power plant generates 8.53 × 10¹⁶ Joule of energy in a year.
1 gram of coal yields generates 36 kilo joule (36000 Joule) energy.
Hence, to generate 8.53 × 10¹⁶ Joule of energy in a year, the weight of carbon burnt will be ;
= 1/36000 x 8.53 × 10¹⁶
= 2.3 x 10¹² gram
