Which material would have the weakest attraction between its particles? a) salt, which is an ionic compound with forces between ions. b) water, which is a polar covalent molecule with hydrogen bonding. eliminate c) nitrogen gas, which is a nonpolar covalent molecule with dispersion forces. d) a diamond, which is a network covalent molecule with bonds between many atoms.

Nitrogen gas, which is a nonpolar covalent molecule with dispersion forces.

Explanation:

Nitrogen gas is a diatomic gas composed of nonpolar covalent bonds. This implies that the gas particles are held together strictly by weak van der Waals forces.

Van der Waals forces represents the weakest level of intermolecular interaction. They are mostly found in nonpolar substances especially gases. Hence, nitrogen gas will exhibit the weakest degree of inter-particle attraction among all the options listed.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
