Answer:
C. The model shows beta decay, whichis not tyoe of nuclear fission
The answer to this is Drinking Waer
Answer: Families of ions that contain NITROGEN, SULFUR, and CARBON follow a pattern similar to that of the polyatomic chlorine ions.
Explanation: Plato
Propane has a molecular formula C3H8.
It is of the form CnH2n+2.
where n = number of C atoms. In present case n = 3.
Each carbon atom in propane is sp3 hydribized. Thus, there are 4 hydrid orbital associated with each carbon atom
The central C atom is sigma bonded to two other carbon atoms and two hydrogen atoms.
Such, sp3 hydridized orbitals are spacial orientated at an angle of

, in order to minimize repulsion between the electrons.
Hence, the c—c—c bond angle in propane, c3h8, is closest to
