Final answer:
The new drying procedure could have either a positive or negative effect on the experimental yield.
Step-by-step explanation:
The new drying procedure had an effect on the experimental yield. In order to understand the effect, it is important to know the specific details of the drying procedure and the experimental setup. Without that information, it is difficult to provide a precise answer. However, a new drying procedure could potentially result in a higher or lower yield depending on factors such as drying time, temperature, and other variables.
