Answer:
Invasive species, runoff pollution, and climate change.
Explanation:
Invasive species, such as Burmese pythons, threaten the Florida Everglades because they are not native to the natural habitat. Pythons eat the native animals, but they don't have any predators.
Pollution from nearby farms and roads enters the water and damages the ecosystem of the Everglades and Louisiana wetlands. Toxic chemicals lead to detrimental effects for both humans and wildlife.
Humans have drained swampy areas to allow for development. However, this has led to the Everglades drying up and even burning in recent years.

See explanation and image attached
Explanation:
The compound SF4 is sulphur tetraflouride. It has a zero formal charge and has a total of 34 valence electrons.
The central atom in the molecule is sulphur in an sp3d hybridization state hence the molecule has a trigonal bipyramidal electron geometry. Since it is a molecule of the sort AX4E; it gives a see-saw molecular shape.
The structure of the molecule is shown in the image attached to this answer.
Answer:
C6H12O6
Explanation:
Just use the table method like I did and compared the molecular mass with the mass of the empirical formula.
