According to VSEPR Theory, the structures of H20 and CH4 would: (select all that apply) have a trigonal pyramidal geometry about the central atom.
have the same number of bonding domains.
have the same electron geometry but different molecular geometries.
have the same electron and molecular geometries.
have the same number of electron domains around the central atom.
Have the same molecular geometry but different electron geometries
have electron domains in a tetrahedral arrangement about the central atom.

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic 

Hello thereone of the following properties was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version. which property fits this description? answer: atomic mass  was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

The answer is not c

Ibelieve it's temperature! i'm not 100% sure.
