Answer:

There are 286 possible combinations

Step-by-step explanation:

To solve this problem we must use the formula of combinations.

nCr =\frac{n!}{r!(n-r)!}

Where n is the number of players that there are and elect r of them

In this case there are 7 + 6 = 13 players and you choose 10 of them

Then we look for  13C10

13C10 =\frac{13!}{10!(13-10)!}

13C10 =\frac{13!}{10!*3!}

13C10 =286

There are 286 possible combinations

The first reaction represented is a decomposition reaction due to the fact the bonded pair are being split apart.

The second equation is a single displacement because the B and C have switched places, which is the only change making it a single displacement. If there had been another bond and A had also moved, it would be double.
