What is waters molecular shape?

Answer 1

Water molecules are symmetric, with mirror symmetry across two planes. Their structure is not constant but varies with local conditions, however the angle between the two hydrogen oxygen bonds is often quoted as 104.52 degrees. (This bent structure is responsible for many of waters interesting properties.)
