The image shows a pendulum that is released from rest at point A. An illustration of a pendulum at 5 different positions. The central position, the equilibrium position is labeled C. The two positions on the left are labeled A and B respectively. The two positions on the right are labeled D and E respectively. All positions are equally spaced.

Which pair of labels is correct?

Which best describes why nh4+ can form an ionic bond with ci-?

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.
