CuBr2 is the formula for copper ii bromide.
The answer to your question is A
It’s Hydrogen Bonding
The vapor pressure of a liquid is the pressure of the vapor produced by evaporation of a liquid or solid above the liquid or solid in a closed container. The hydrogen bonding between liquid water molecules explains why water has an unusually low vapor pressure.
The amount of coal burnt each year to produce 8.53 × 10¹⁶ Joule of energy is 2.3 x 10¹² gram.
<h3>
What is Combustion?</h3>
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
