the physical and chemical properties of the substances and how they react chemically

Answer 1

Before Ella combines substances to form a new material, the most important thing she needs to know is:

The physical and chemical properties of the substances and how they react chemically.

Understanding the properties of the substances will help her predict how they will interact, whether they will react to form a new material, and what kind of material will result. This knowledge is crucial for ensuring safety and achieving the desired outcome in her material creation.
