Question

1. drag and drop the definitions with the terms.

a substance made up of two or more atoms that are chemically bonded together
a compound that contains carbon and hydrogen
a compound that does not contain carbon

1. choose the best answer.

which statement is true?
all molecules are compounds, but not all compounds are molecules.
all compounds are molecules, but not all molecules are compounds.
compounds and molecules are the same thing.

Explanation:

1)

• A molecule is defined as a substance made up of two or more atoms that are chemically bonded together.
• An organic compound is a compound that contains carbon and hydrogen.
• An inorganic compound is a compound that does not contain carbon (with some exceptions like \(CO_2\) which are still classified as inorganic).

• A molecule is a group of atoms bonded together. A compound is a substance formed when two or more different elements are chemically bonded.
• All compounds are molecules (since they have atoms bonded), but not all molecules are compounds. For example, \(O_2\) is a molecule (two oxygen atoms bonded) but not a compound (because it has only one type of element).

Answer:

• "a substance made up of two or more atoms that are chemically bonded together" → molecule
• "a compound that contains carbon and hydrogen" → organic compound
• "a compound that does not contain carbon" → inorganic compound
