<h2>Answer : Daniel was related to study of Earth and Space
</h2><h2>Whereas Sanya was closely related to chemistry</h2><h3>Explanation :</h3>
As in the given information, Daniel the scientist was studying the effect of tropical storms on coastal erosions. These studies comes under the field of Earth and Space. Earth because coastal erosions are involved in the study, and Space because storms are discussed which is something related to space.
In case of Sanya, it is clear that her study focuses on discharges from the industrial plant that has effect on freshwater swamps. Precisely, she is studying the pH concentration which comes in chemistry.
This prove that Daniel studies Earth and Space whereas Sanya studies Chemistry.
Answer: The value of
is 1118 .
Explanation:
To calculate the number of moles, we use the equation:
The balanced chemical reaction is:
Given :
Energy released when 0.288 mole of
is reacted = 161 kJ
Thus Energy released when 2 moles of
is reacted =
Thus the value of
is 1118.
