When coffee is added to water, that is a physical change. The coffee does not undergo a chemical reaction, the various chemical constituents of coffee remain the same. What changes is that the coffee is dissolved in water. If the water were to evaporate, leaving the coffee behind, it would be the same as it was (not counting the loss of some volatile constituents which would also evaporate, along with the water) before it was added to water.
