Answer:
Ion-dipole forces
Explanation:
Na⁺ is a cation, that is, an ion with a positive charge.
NH₃ has polar covalent bonds (due to the difference in electronegativity between nitrogen and hydrogen). According to the VESPR theory, it has a trigonal pyramidal shape with a lone pair. As a consequence, it has a net dipole moment and the molecule is polar.
The intermolecular forces between Na⁺ (ion) and NH₃ (dipole) are ion-dipole forces.
Hmm the answer is 2.454
No explanation needed it’s just 2.454
There are three methods of thermal energy transfer: conduction, convection, and radiation. Air molecules that come into contact with the warmer land and surface of the oceans and lakes increase their thermal energy through conduction.
