Letting a = red spheres and b = blue spheres, write a balanced equation for the reaction. express your answer as a chemical equation.

Knowing that the a and b represents red and blue spheres respectively. The chemical equation we could make isL5A2 + 5B - - > 4A2B + A2 + B as shown in boxes

Simplifying this would make it:

4A2 + 4B - - > 4A2B

Thus, reducing the coefficients, the final answer is:

A2 + B - - > A2B
