Answer:
D. Mass is the amount of matter and weight is the effect of gravity on mass.
Explanation:
Mass is, by definition, the amount of matter that makes up an object. The weight of an object is directly related to the pull of gravity.
The correct answer is "D".
Hope this helps!
Answer is: B an ionic bond because the Cl atom pulls electrons off the Cs atom resulting in a positive ion and negative ion that are attracted to each other.
Ceasium is alkaline metal, with low electronegativity, which means it easily gives one electron, and forms positive cation and chlorine is nonmetal, with high electronegativity, it gains electron and forms negative anion.
NaCl : In case of Sodium chloride Ionic bonding exists, as sodium is a cation and chloride is an anion. So, these two opposite charged species will attract each other and form ionic bond.
HF : In case of Hydrogen fluoride, Hydrogen bond interactions are found this is because when hydrogen is attached to either Oxygen, Nitrogen or Fluorine atom it gets involve in hydrogen bonding interactions with the neighbor oxygen, nitrogen or fluorine atom (highly electronegative).
HCl : In Hydrogen chloride dipole dipole interactions exist. A partial positive hydrogen atoms interacts with a partial negative chlorine atom of neighbor molecule.
F2 : As fluorine molecule is neutral and charge less, so it will interact with another fluorine molecule through London dispersion forces.
