IT COVERS 10% OF EARTH'S TOTAL LAND
Explanation:
Answer:
4 : 3
Explanation:
The balanced chemical equation is given as follows:
2Al₂O₃ ..............> 4Al + 3O₂
Now, from this equation we can note that:
For every 4 moles of aluminum moles produced, corresponding 3 oxygen moles are produced.
This means that the ratio between the formation of aluminum to the formation of oxygen moles is 4:3
Hope this helps :)

Explanation: Studying stem cells can help scientists understand more about how the body works and how disease develops and affects the body. Working with stem cells may help researchers better understand different diseases and conditions, and find new treatments.
Answer:
1.12x10²³ atoms of F
Explanation:
A molecule is a group of 2 or 3 atoms that are bonded by electrostatic charges.
In 1 molecule of MgF2 there are 2 atoms of fluorine and 1 atom of magnesium.
Thus, there are 2 atoms of fluorine per molecule of MgF2. In 5.6x10²² molecules:
5.6x10²² molecules MgF2 * (2 atoms Fluorine / 1 molecule MgF2) =
<h3>1.12x10²³ atoms of F</h3>
