For questions 11-15
11. Magnesium Oxide is a combination between Magnesium and oxygen so the formula will be MgO
12. Calcium Chloride is a combination between Calcium and Chlorine, so the formula will be CaCl₂ the ₂ comes from the fact that there is two Chlorine atoms
13. Lithium Sulfide is a combination between Two lithium and a sulfur atoms,
so the formula will be Li₂S The ₂ coming from the two lithium atoms
14. Barium Selenide is a combination between Barium and Selenium so the formula will be BaSe
15. Aluminum Oxide is a combination between Aluminum and Oxygen, there are two Aluminum atoms and three Oxygen atoms, so it will make Al₂O₃
Hope this helps
<span>Deforestation affects biogeochemical cycling mainly by disrupting the water cycle, causing water to be lost more rapidly from the ecosystem and with it important elements and nutrients. this was from socratic.com, it isnt my words but its an answer </span>
The approach to development that suggests that there are five levels of the environment that simultaneously influence individuals is Bronfenbrenner's bioecological approach.
These five levels include: microsystem, mesosystem, exosystem, macrosystem, and chronosystem. All of these levels have an impact on human beings together, and at the same time, and shape people to become the persons they are throughout their lives.
Would this be speciation?
