Answer:
we need the model to answer
Explanation:
Answer: The molecular formula of the molecule is 
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
The given compound contains one carbon atom, four hydrogen atoms and one oxygen atom.
It is an alcohol with functional group -OH and with molecular formula of named as methanol.
The molecular formula of the molecule is
This is because stronger intermolecular bonds require more energy to break. As this energy is supplied in the form of heat when boiling, substances with stronger bonds will have a higher boiling point. The order of strength of intermolecular forces is; London dispersion forces < dipole-dipole<span> < </span><span>Hydrogen bonding</span>
Answer: a)neptunium b) the element is unstable
Explanation:
a) 238 0 239 -1
U + n = Np e
92 1 93 0
b) it is an isotope of neptunium with half-lives less than 4.5 days, with most less than 50 minutes. It is therefore not stable that's why they where unable to identify it
