What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. It consists of only one type of atom.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together in a fixed ratio.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent).

Front

What does a diagram showing different colored circles represent?

Back

The different colored circles represent atoms of different elements.

Front

What is the difference between a pure substance and a mixture?

Back

A pure substance has a uniform and definite composition, while a mixture contains two or more substances that retain their individual properties.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout, such as a solution.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture where the components are not uniformly distributed, and different parts can be seen.

Front

What is the law of definite proportions?

Back

The law of definite proportions states that a chemical compound always contains its component elements in fixed ratio by mass.

Front

What is the law of multiple proportions?

Back

The law of multiple proportions states that when two elements form more than one compound, the ratios of the masses of one element that combine with a fixed mass of the other can be expressed in small whole numbers.
