Answer :
Answer:
Double replacement.
Explanation:
Chemical Reactions => Double Replacement Reactions.
Let's call Ted as T, Emily as E, Jack as J, and Brenda as B.
In the first match, we have T and E playing against J and B; and in the second match, we have T and B playing against J and E. We can state a 'reaction' of this if the first match would be the reactants and the second match the products:
[tex]TE+JB\rightarrow TB+JE.[/tex]You can note that this is similar to a double replacement reaction, remember that a double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:
[tex]AB+CD\rightarrow AD+BC,[/tex]which is similar to the reaction of the game, so the answer would be Double replacement.
