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

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
