Answer:
Structure has been shown below
Explanation:
- In a Lewis structure, least electronegative atom is taken as central atom (except H)
- Total valence electrons of constituting atoms are used to construct Lewis structure
- A bond between two atoms are represented by a horizontal line or a dotted line (two dots).
- Spatial rearrangement of atoms are neglected in Lewis structure.
- H has one valence electron and O has six valence electrons. So, total valence electrons in are 8
- Lewis structure of has been given below.
If it is in pure form, then only one type of atom. Negating if it has partially oxidized
Sc (neutral) [Ar] 3d1 4s2
Sc+ [Ar] 3d1 4s1
Sc2+ [Ar] 3d1
hope this helped!
Answer:
d) gases that absorb infrared radiation
water vapor, carbon dioxide, methane, and other trace gasses in the Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from the Earth's surface.
Their tentacles act as propellers to help with a speedy escape
