such as when sodium and chlorine combine, they form salt which is obviously harmless
Suppose an animal ate poisonous element A and then poisonous element B. Both elements would join together in the animal's tummy. As a consequence, the animal would be DEAD and I guess we could say transformed into a completely harmless substance. I hope you are satisfied with my answer. I really went out of my ways to please you. Thank you for posting at WikiAnswers!
Compound.
a chemical reaction
A reaction between two substances or the decomposition of a substance are chemical changes.
mixture
a synthesis reaction
Think a bit sciency if you say something like 'Please combine these two substances to make this substance' for example (whatever the substance might be)
synthesis reaction
Chemical change
Yes, the ability to combine with another substance is a physical property that depends on the chemical composition and structure of the substances involved. The physical properties of the substances, such as molecular size, polarity, and intermolecular forces, determine how easily they can combine with each other.
The ability to combine chemically through the formation of chemical bonds with another substance is a chemical property.
When two substances combine chemically, the properties of the products are different from those of the starting materials. This is because new chemical bonds are formed, leading to a different arrangement of atoms and different chemical properties.
