Ted and emily played a mixed doubles tennis match against jack and brenda. in the second match. ted and brenda played against jack and emily. which type of chemical reaction does the situation demonstrate?

Explanation:

The situation is describing how two couples, Ted&Emily and Jack&Brenda exachange partners to form two new couples, Ted&Brenda and Jack&Emily.

This is, the partners swift places. That is exactly what happens in the double replacement reactions.

Double replacement reactions can be represented by:

That representation means that the compound AB (formed by the ions A⁺ and B⁻) exchanges ions with the compound CD (formed by the ions C⁺ and D⁻), to form two new compounds, AD and BC.

You might use the first letters of the names of the given players to represent the situation in a similar way:

        ↑                       ↑                            ↑                           ↑

  Ted & Emily     Jack & Brenda     Ted & Brenda     Jack & Emily

A good analogy to show that in a double replacement reactions the ions of two reactant compounds swift places, just like mixed double tennins teams can do, to form two new products.

C) Double replacement
