molecular structure

Front

What is the solid state of matter characterized by?

Back

The solid state of matter is characterized by strong forces of attraction between particles that keep them in fixed positions.

Front

Why does oil not dissolve in water?

Back

Oil does not dissolve in water because oil is made of nonpolar molecules, while water is made of polar molecules.

Front

What do subscripts in a chemical formula indicate?

Back

Subscripts in a chemical formula indicate the number of each type of atom present in the compound.

Front

What are nonmetals generally composed of at room temperature?

Back

Nonmetals are generally composed of individual atoms or small molecules and are often gases at room temperature.

Front

What property is likely to be found in a substance composed of a metal and a nonmetal?

Back

A substance composed of a metal and a nonmetal is likely to have a high melting point.

Front

Define molecular structure.

Back

Molecular structure refers to the arrangement of atoms within a molecule, including the bonds between them.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a partial positive charge on one side and a partial negative charge on the other, due to uneven distribution of electrons.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is a molecule that has an even distribution of electrical charge, meaning it does not have distinct positive or negative poles.

Front

What is the difference between a compound and a mixture?

Back

A compound is a substance formed when two or more elements chemically bond together, while a mixture is a combination of two or more substances that retain their individual properties.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow; higher viscosity means the fluid flows more slowly.
