First, you need to calculate the standard cell potential using standard reduction potential from a textbook or online. Since Mg becomes Mg+2, magnesium is being oxidized because it is losing electrons, you need to flip its potential
Fe+2 + 2e- --> Fe potential= -0.44
Mg+2 + 2e- --> Mg potential= -2.37
Cell potential= (-0.44) + (+2.37)= 1.93 V
Now, you need to use Nernst formula to get the answer. I have attached a PDF with the work.
Its the hydrogen bonding between hydrogen and oxygen in the water molecule
Hi!
Claudius Ptolemy was an astronomer who wrote the only surviving ancient treatise on astronomy. He proposed his famous theory on the Almagest. In this model, the Earth was on the center, and the Moon, Mercury, Venus, the Sun, Mars, Jupiter, Saturn, and the stars (in that order) were rotating around the Earth.
This famous theory is called the Geocentric Theory (Teoria Geocêntrica in Portuguese).
<u>Answer:</u>
It helped biologists collect data on when and where turtles travel.
<u>Explanation:</u>
Green sea turtles need to be conserved so the biologist take help of satellites in order to track down green sea turtles.
The tracking of green sea turtles can be done by the help of satellites as satellites send a signal whenever these turtles come to surface of water to breathe which can then be used to prevent the turtles from getting caught by poachers.
