ANSWER
option B
EXPLANATION
Firstly, we will need to define the standard heat of formation
The standard heat of formation is the amount of heat evolved or absorbed when one mole of a compound is completely formed from its constituent elements under standard conditions.
From the options provided, you will see that only option B aligns with the definition of the standard heat of formation.

From the above reaction, you will see that 1 mole of water is formed from hydrogen and oxygen.
Hence, the answer is option B
Answer:
the same number of atomic orbitals.
Explanation:
Answer:
B) There is more water in the air because the rate of evaporation increases
Explanation:
As the temperatures rise across the globe, the rate of evaporation also increases, resulting in more water in the air. The reason for the increased evaporation is that the ice sheets and glaciers are melting, thus there's more liquid water. The more liquid water there is, the more evaporation there will be. As the evaporation increases, there will be an increase in the formation of clouds, thus there will be more precipitation around the world, gradually leading to warmer and wetter climate.
