What determines whether two substances are the same or different?

Back

Two substances are considered different if they have different properties.

Front

How do the repeating groups of atoms in a substance affect its properties?

Back

The properties of a substance are influenced by the arrangement and type of atoms in its repeating groups; different arrangements lead to different properties.

What role do chemical properties play in distinguishing substances?

Back

Chemical properties, such as reactivity with other substances, can help distinguish substances and predict how they will behave in chemical reactions.

Front

Why might two substances with similar appearances have different properties?

Back

Two substances may have similar appearances but different properties due to differences in their molecular structure or composition.
