Answer:
C. Pangaea contained all of Earth's continental crust.
Explanation:
Pangaea is the name given to the supercontinent that contained almost all of the landmass on Earth. The remaining area was ocean.
Structure 1 is satisfying octet rule because each atom surrounded by 8 electrons:
The valance electron for oxygen is 6, for sulfur is 6, but for hydrogen is 1. Therefore, the molecule has <span>valance electrons. Sulfur is bonded with 4 oxygen atoms, 4 single bonds, whereas 2 hydrogen atoms are bonded with 2 oxygen atoms.
But the actual structure is 2 but it violates octet rule since S is surrounded in this case with 12 electrons

elliptical/ellipse
Explanation:
» <u>Concepts</u>
Astronomer <u>Johannes Kepler</u> discovered and founded his three laws of planetary motion. One of these laws states that the orbit of <u>all</u> planets, including Earth, is in an elliptical shape rather than a circle.
Answer:
AlF3
Explanation:
Aluminum fluoride is an inorganic compound of chemical formula AlF3. Such a compound originates from the treatment of aluminum hydroxide particles with hydrogen fluoride, which react and give rise to aluminum fluoride. This is a very important solid and crystalline element during the production of other compounds that use aluminum oxides because it has the ability to lower the melting point.
