 #### How can I add coefficients to balance my reaction?
 
-- **Answer:** To balance your equation, changing coefficients is still not possible, so you need multiple samples to express a single molecule when it has a coefficient more than one. This step is important for correct calculations of the yield.
+- **Answer:**  Yes, coefficient to balance your equation can be added in the reaction table (since v1.4.0). Those coefficients are not yet displayed in the reaction image but we are working on this.
