Question

You have two solutions and want to find how two chemicals react. Solution A has 100 mL of 1.0 M particle A. Solution B has 100 mL of 1.0 M particle B. You combine the two solutions and find the new concentrations of A and B to both be 0.50 M.

Answer 1

There was no reaction

Step-by-step explanation:

1.Did a reaction occur? Explain your answer. If a reaction occurred, also provide a possible chemical equation describing the reaction.

When a reaction occurs, the initial moles of each species decreases to produce a determined product. If the initial moles of reactant = final moles there was no reaction:

Initial moles A:

0.100L * (1.0mol / L) = 0.100 moles A

Final moles A:

0.200L * (0.5mol / L) = 0.100 moles A

Initial moles B:

0.100L * (1.0mol / L) = 0.100 moles B

Final moles B:

0.200L * (0.5mol / L) = 0.100 moles B

As the moles in the beginning = Moles after the mixture

There was no reaction
