Answer:
c. a proton
Explanation:
A neutron is most equal in mass to a proton.
A neutron is a subatomic particle without any charges on them.
A proton is a subatomic particle with a positive charge.
- the mass of a proton and neutron are the most similar in an atom.
- the mass of a proton is 1.67 x 10⁻²⁷kg
- So also is the mass of a neutron
- the mass of an electron is 9.11 x 10⁻³¹kg
Answer:
None of these statements are true
Explanation:
(a)
Heavier and large molecules or atoms exhibit greater dispersion force than lighter ones due to easily form temporary dipoles by large molecule.
(b)
Compounds with hydrogen bonding usually have higher boiling point than that of similar compound without hydrogen bonding,
Because boiling point of a compounds depends on force of attraction between the molecules.
(c)
Non polar compounds usually have lower boiling points than polar compounds of similar mass due to dipole dipole attractive force of polar compound.
