Whether or not they are within the same group (vertical columns) within the periodic table, determines similarity of chemical properties.
The hybridization of the central carbon compound CH4 tetrahedral is
SP^3 hybridization
In tetrahedral molecular geometry a central atom is located at the center with 4 substituent that are located at the corners of tetrahedron. Example in methane molecules is made up of b equally spaced sp^3 hybrid orbital forming bond angle of 109.5
A, Compression
Compression of a gas always requires work
A. will lead to an increase in marine organisms
