It means that the 4 hydrogen atoms of a methane molecule are at the vertices of a regular tetrahedron with the carbon atom at its centre.
If "mi then" is meant to be methane, then the answer is approx 0.00018%
1 ratio 5 is the fixed ratio of atom in a molecules...
in geometry...it means that the measure of the angles adds up to 90 degrees
The common leg of two angles.
polar bears!
It is a flat two dimensional surface which extends to infinity in all directions.
Stigmatism doesn't meant anything in geometry and is not even a word. Astigmatism, however, is where rays in an optical system propagate in two perpendicular planes that have different focus.
There's no such molecule; elements cannot combine that way. If you meant H10C4, then it's a structural isomer of butane. (Butane or 2-methylpropane.)
According to Euclidean geometry, that is an object where all the angles are the same and all the sides are the same length.
Rise over run, generally change in y-coordinates divided by change in x-coordinates.
Ozone is a chemical which is a type of oxygen molecule. It is three atoms of oxygen combined.
You meant to say....how many atoms does one molecule have. That will depend. For example..... 1 molecule of CH4 has 5 atoms.......1 molecule of C6H12O6 has 24.....and 1 molecule of H2O2 has 4 atoms. Hope this helps. Dr Jim Romano CEO Orgoman.com
