Properties of the Matter

What is this?...

• Atoms of an element

• Molecules of a compound

• Mixture of elements and a compound

• Molecules of an element

What is study chemistry?

• The structure of the matter and how the atoms are arranged

• Composition and structure of the matter

• All the previous answers

• The properties of the mass

The sicentific method is...

• Observations and experiments (who cares about results?)

• When observations repeatedly lead to the same consistent results

• The explanations of the results: hypotheses

• Methodology to find patterns and describe laws in order to develop theorie

There are two kind of pure substance:

Do not depend of the amount of sample and can be observed without changing the identity and composition of the substance

• Intensive Properties and Chemical properties

• Physical and Intensive properties

• Chemical and Extensive properties

• Physcal Properties and Extensive Properties

Exstensive properties (not) depend on the amount of sample

• Verdadero

• Falso

When we say that lead is a denser metal than aluminum, are we talking about an extensive or intensive property?
