It's C3V
It has
E
2 C2 ( one clockwise, the other anticlockwise) and they are labelled as C2+ and C2- respectively
3 vertical mirror planes, each goin through one of the N-H bonds
It has 2C3 not 2C2
C3v
Ammonia solution consists of ammonium hydroxide and water, the ammonium hydroxide is basic (due to the hydroxyl functional group). Dry ammonia doesn't have this functional group.
Flash point for ammonia is the point where it becomes flammable after a phase change from a liquid to gas forming a flammable mixture in air. Obviously this is different to the lowest flammable concentration in air. In the case of ammonia it is 11 degrees according to the MSDS: http://msds.chem.ox.ac.uk/AM/ammonia_anhydrous.html
It forms a white crystalline mass. Ammonia freezes at -107 degrees C.
Because of its hydrogen bonding.

C3v
The Cs point group only has one symmetry plane. Cl2CH2 has two symmetry planes and one C2 axis. The mirror plane is perpendicular to the rotation axis, so this makes the point group C2h.
Line symmetry = Reflection symmetry. Point symmetry = Rotational symmetry.
It is a line through the point of symmetry. In general it is not an axis of symmetry.
The letters S and N have point symmetry but not line symmetry.
You are thinking of the ammonium radical, NH4-.

The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius
No, a triangle does not have point symmetry. Point symmetry occurs when an object or shape remains the same after being rotated 180 degrees around a central point. In the case of a triangle, it does not have point symmetry because it does not look the same after a 180-degree rotation.
