15. Which statement A-D about chemical bonds is atic potential energy goes through a
minimum. minimum occurs is called the bond length. d. As two atoms come togcther, the
electrostatic po The distance between the atoms at which thns two atoms inti energy together at a
distance that minimizes the elecpositively b. The bond energy is the energy released when
twochearged nuci occurs is ca een the atoms at which this ergy released when two atoms
infinitely far a stance that minimizes the electrostatic potentia d. ectrostatic ely charged electrons
to the positively charged nuc The repulsion of the negatively charged cle energy to decrease as
two atoms come together. when negatively charged electrons with each other and the positively
the two atoms are very close together other causes the electrostatic potential energy to increase e.
Statements A-D are all correct at 70.0°C is
Solution
Ans is C. Because when two atoms close together potential energy is extremely high due to
increase in repulsion between electrons.
