• Organic compounds contain carbon atoms, while inorganic compounds contain hydrogen atoms.
• Organic compounds are found in living organisms, while inorganic compounds are found in non-living things.
• Organic compounds are generally more reactive than inorganic compounds.
• Organic compounds contain carbon and hydrogen bonds. Most inorganic compounds do not contain carbon.

What are models and why are the used in science?

• Models are used in science to visualize data and make it easier to understand.
• Models are used in science to create simulations of natural or artificial processes.
• Models are used in science to collect and analyze data.
• Models are representations of the experiment that allows the scientist to easily observe and gather data.

• Models are used in science to test hypotheses and theories.

How is a scientific theory different from a law?

• A scientific theory is based on empirical evidence, while a scientific law is based on mathematical equations.
• A scientific theory is an explanation, while a scientific law is a description.

• A scientific theory is more widely accepted than a scientific law.
