A student adds a solution of Pb(NO3)2(aq) to a solution of Na3PO4(aq), and a white precipitate forms. Which of the following is the net-ionic equation for the observed reaction?

Occurs in substances that have at least one non-metal

Explanation:

The intersection point which is space B is the place where both ionic and covalent bonds shares the same properties.

An ionic bond is formed by the transfer of electrons from a metal to receiving non - metal.

A covalent bond is formed by the sharing of electrons between non - metals.

For an ionic and covalent bond to form, there must be a non -metal. Therefore, from the Venn- diagram the meeting point for both bonding types is that there must be a non - metal for the bonding association to occur.
