Consider a specific chemical reaction represented by the equation aa + bb → cc + dd. in this equation the letters a, b, c, and d represent chemicals, and the letters a, b, c, and d represent coefficients in the balanced equation. how many possible values are there for the quantity "c"?

The answer to your question is:  c = a + b - d

Explanation:

                           aA  +   bB   →   cC   +   dD

c  could have any number from 1 to the number necessary in order that the

    equation be balanced.

        For example

                                 c + d = a + b

                                 c = a + b - d        

If a = 1; b = 3   and d = 2

then                        c = 1 + 3 - 2

                              c = 2,

etc.              

i'm pretty sure it is letter c.) car
