<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.
The magnet's north pole would point to the Earth's south pole and the magnet's south pole would point to the Earth's north pole.
<u>Explanation</u>:
- There is a magnetic pole in the earth and the magnetic poles of the earth run using the equator and it has both the closures at the arctic pole and the Antarctic pole. The attractive positive field or the north pole is situated in the arctic zone and the south pole is situated in the Antarctic zone.
- The magnetic positive field or the north pole is situated in the arctic zone. Any magnet which is allowed to rotate whenever suspended on the outside of the earth will align itself with the magnetic field of the earth. That is the way the bar magnet orients itself comparative with this current planet's magnetic field.
Explanation:
20.0 moles= 80.1 or 80.05g
5.00 moles= 20.0g
1.20×1025moles= 4923.2g
1.00 moles= 4.00g
80.0 moles= 320.2g
The Farenheit and Celcius scales can have negative numbers
Noble gases:) they are very non-reactive
