Question 5(Multiple Choice Worth 4 points) [RM.01] Bauxite is the chief ore from which aluminum is extracted. Which of these statements is correct about bauxite? It has a definite crystal structure. It does not have a definite chemical composition. Its atoms do not arrange themselves in a definite order. Its molecules are made up of a different number of atoms.

## Step 1<br />Bauxite is a naturally occurring mineral, which means it is a solid substance that is found in nature. It is the primary ore from which aluminum is extracted.<br /><br />## Step 2<br />Bauxite does not have a definite crystal structure. This is because it is not a pure substance, but a mixture of various aluminum hydroxides. This means that the atoms in bauxite do not arrange themselves in a definite order, which is a characteristic of a crystal structure.<br /><br />## Step 3<br />Bauxite does not have a definite chemical composition. This is because it is a mixture of various aluminum hydroxides, which means the ratio of the atoms in the molecules can vary.<br /><br />## Step 4<br />The molecules of bauxite are made up of a different number of atoms. This is because bauxite is a mixture of various aluminum hydroxides, which means the number of atoms in the molecules can vary.
